Hortonworks HDPCD Hortonworks Data Platform Certified Developer https://killexams.com/pass4sure/exam-detail/HDPCD Question: 97 You write MapReduce job to process 100 files in HDFS. Your MapReduce algorithm uses TextInputFormat: the mapper applies a regular expression over input values and emits key- values pairs with the key consisting of the matching text, and the value containing the filename and byte offset. Determine the difference between setting the number of reduces to one and settings the number of reducers to zero. A. There is no difference in output between the two settings. B. With zero reducers, no reducer runs and the job throws an exception. With one reducer, instances of matching patterns are stored in a single file on HDFS. C. With zero reducers, all instances of matching patterns are gathered together in one file on HDFS. With one reducer, instances of matching patterns are stored in multiple files on HDFS. D. With zero reducers, instances of matching patterns are stored in multiple files on HDFS. With one reducer, all instances of matching patterns are gathered together in one file on HDFS. Answer: D Explanation: * It is legal to set the number of reduce-tasks to zero if no reduction is desired. In this case the outputs of the map-tasks go directly to the FileSystem, into the output path set by setOutputPath(Path). The framework does not sort the map-outputs before writing them out to the FileSystem. * Often, you may want to process input data using a map function only. To do this, simply set mapreduce.job.reduces to zero. The MapReduce framework will not create any reducer tasks. Rather, the outputs of the mapper tasks will be the final output of the job. Note: Reduce In this phase the reduce(WritableComparable, Iterator, OutputCollector, Reporter) method is called for each The output of the reduce task is typically written to the FileSystem via OutputCollector.collect(WritableComparable, Writable). Applications can use the Reporter to report progress, set application-level status messages and update Counters, or just indicate that they are alive. The output of the Reducer is not sorted. Question: 98 Indentify the utility that allows you to create and run MapReduce jobs with any executable or script as the mapper and/or the reducer? 51 A. Oozie B. Sqoop C. Flume D. Hadoop Streaming E. mapred Answer: D Explanation: Hadoop streaming is a utility that comes with the Hadoop distribution. The utility allows you to create and run Map/Reduce jobs with any executable or script as the mapper and/or the reducer. Reference: http://hadoop.apache.org/common/docs/r0.20.1/streaming.html (Hadoop Streaming, second sentence) Question: 99 Which one of the following statements is true about a Hive-managed table? A. Records can only be added to the table using the Hive INSERT command. B. When the table is dropped, the underlying folder in HDFS is deleted. C. Hive dynamically defines the schema of the table based on the FROM clause of a SELECT query. D. Hive dynamically defines the schema of the table based on the format of the underlying data. Answer: B Question: 100 You need to move a file titled “weblogs” into HDFS. When you try to copy the file, you can’t. You know you have ample space on your DataNodes. Which action should you take to relieve this situation and store more files in HDFS? A. Increase the block size on all current files in HDFS. B. Increase the block size on your remaining files. C. Decrease the block size on your remaining files. D. Increase the amount of memory for the NameNode. E. Increase the number of disks (or size) for the NameNode. 52 F. Decrease the block size on all current files in HDFS. Answer: C Question: 101 Which process describes the lifecycle of a Mapper? A. The JobTracker calls the TaskTracker’s configure () method, then its map () method and finally its close () method. B. The TaskTracker spawns a new Mapper to process all records in a single input split. C. The TaskTracker spawns a new Mapper to process each key-value pair. D. The JobTracker spawns a new Mapper to process all records in a single file. Answer: B Explanation: For each map instance that runs, the TaskTracker creates a new instance of your mapper. Note: * The Mapper is responsible for processing Key/Value pairs obtained from the InputFormat. The mapper may perform a number of Extraction and Transformation functions on the Key/Value pair before ultimately outputting none, one or many Key/Value pairs of the same, or different Key/Value type. * With the new Hadoop API, mappers extend the org.apache.hadoop.mapreduce.Mapper class. This class defines an 'Identity' map function by default - every input Key/Value pair obtained from the InputFormat is written out. Examining the run() method, we can see the lifecycle of the mapper: /** * Expert users can override this method for more complete control over the * execution of the Mapper. * @param context * @throws IOException */ public void run(Context context) throws IOException, InterruptedException { setup(context); while (context.nextKeyValue()) { map(context.getCurrentKey(), context.getCurrentValue(), context); } cleanup(context); 53 } setup(Context) - Perform any setup for the mapper. The default implementation is a no-op method. map(Key, Value, Context) - Perform a map operation in the given Key / Value pair. The default implementation calls Context.write(Key, Value) cleanup(Context) - Perform any cleanup for the mapper. The default implementation is a no-op method. Reference: Hadoop/MapReduce/Mapper Question: 102 Which one of the following files is required in every Oozie Workflow application? A. job.properties B. Config-default.xml C. Workflow.xml D. Oozie.xml Answer: C Question: 103 Which one of the following statements is FALSE regarding the communication between DataNodes and a federation of NameNodes in Hadoop 2.2? A. Each DataNode receives commands from one designated master NameNode. B. DataNodes send periodic heartbeats to all the NameNodes. C. Each DataNode registers with all the NameNodes. D. DataNodes send periodic block reports to all the NameNodes. Answer: A Question: 104 In a MapReduce job with 500 map tasks, how many map task attempts will there be? 54 A. It depends on the number of reduces in the job. B. Between 500 and 1000. C. At most 500. D. At least 500. E. Exactly 500. Answer: D Explanation: From Cloudera Training Course: Task attempt is a particular instance of an attempt to execute a task – There will be at least as many task attempts as there are tasks – If a task attempt fails, another will be started by the JobTracker – Speculative execution can also result in more task attempts than completed tasks Question: 105 Review the following 'data' file and Pig code. Which one of the following statements is true? A. The Output Of the DUMP D command IS (M,{(M,62.95102),(M,38,95111)}) B. The output of the dump d command is (M, {(38,95in),(62,95i02)}) C. The code executes successfully but there is not output because the D relation is empty D. The code does not execute successfully because D is not a valid relation Answer: A Question: 106 Which one of the following is NOT a valid Oozie action? 55 A. mapreduce B. pig C. hive D. mrunit Answer: D Question: 107 Examine the following Hive statements: Assuming the statements above execute successfully, which one of the following statements is true? A. Each reducer generates a file sorted by age B. The SORT BY command causes only one reducer to be used C. The output of each reducer is only the age column D. The output is guaranteed to be a single file with all the data sorted by age Answer: A Question: 108 Your client application submits a MapReduce job to your Hadoop cluster. Identify the Hadoop daemon on which the Hadoop framework will look for an available slot schedule a MapReduce operation. A. TaskTracker B. NameNode C. DataNode D. JobTracker E. Secondary NameNode 56 Answer: D Explanation: JobTracker is the daemon service for submitting and tracking MapReduce jobs in Hadoop. There is only One Job Tracker process run on any hadoop cluster. Job Tracker runs on its own JVM process. In a typical production cluster its run on a separate machine. Each slave node is configured with job tracker node location. The JobTracker is single point of failure for the Hadoop MapReduce service. If it goes down, all running jobs are halted. JobTracker in Hadoop performs following actions(from Hadoop Wiki:) Client applications submit jobs to the Job tracker. The JobTracker talks to the NameNode to determine the location of the data The JobTracker locates TaskTracker nodes with available slots at or near the data The JobTracker submits the work to the chosen TaskTracker nodes. The TaskTracker nodes are monitored. If they do not submit heartbeat signals often enough, they are deemed to have failed and the work is scheduled on a different TaskTracker. A TaskTracker will notify the JobTracker when a task fails. The JobTracker decides what to do then: it may resubmit the job elsewhere, it may mark that specific record as something to avoid, and it may may even blacklist the TaskTracker as unreliable. When the work is completed, the JobTracker updates its status. Client applications can poll the JobTracker for information.

Black+Decker makes mostly lightweight, plug-in electric leaf blowers. Its leaf blowers are among the most widely available and can be found at mass merchants, home centers, online retailers, and hardware stores. In general, its models are inexpensive. The Craftsman gas leaf blower line includes handhelds and backpacks, while its electrics include both corded and cordless models. Craftsman is now owned by Stanley Black+Decker, with many tools available at local hardware stores, as well as at Lowe’s. DeWalt is the premium brand from Stanley Black+Decker, and its products are generally made for serious DIYers as well as pros. It makes cordless leaf blowers on a 60-volt battery platform. The batteries can also be used in electric string trimmers, lawn mowers, and hedge trimmers from the brand. Echo makes professional-grade handheld and backpack leaf blowers, most of which run on gas. In exact years, it has added a battery handheld platform. Echo’s leaf blowers are available at Home Depot, Walmart, outdoor power-equipment dealers, and hardware stores. Ego makes battery-powered handheld and backpack-style blowers. Its leaf blowers use the same 56-volt battery that powers the company’s electric lawn mowers, string trimmers, chainsaws, and snow blowers. The manufacturer’s leaf blowers and other outdoor power tools are available online and at Lowe’s. A major manufacturer of gas-powered outdoor power equipment, Swedish brand Husqvarna makes leaf blowers, chainsaws, and string trimmers, among other tools. It makes premium handheld gas and battery blowers, as well as backpack blowers, many of which are marketed to professionals. Its products are sold at local dealers, Lowe’s, and Walmart. Kobalt is a Lowe’s-exclusive brand of leaf blowers, string trimmers, mowers, and other outdoor power equipment. Kobalt makes primarily battery handheld leaf blowers. Like other brands, its models rely on a single battery platform, in this case a 40-volt battery, that can be used to power any of these tools. Makita is a high-end tool brand that now makes electric outdoor power equipment. Many of its cordless leaf blowers are powered by two 18-volt batteries instead of one larger battery. The advantage is that these smaller batteries can each be used in hundreds of other cordless tools, such as cordless drills, impact drivers, or multi-tools. Its leaf blowers are sold at Home Depot and Walmart, as well as on Amazon. The house brand at Home Depot, Ryobi is a major manufacturer of leaf blowers in most configurations, particularly handhelds. It makes gas and battery handheld leaf blowers, as well as gas-powered backpack units. Stihl makes professional-grade gas leaf blowers and high-end electric models. It sells exclusively through outdoor power-equipment dealers. Stihl uses the HomeScaper line name on some consumer-grade outdoor power equipment. Another leading brand of electric leaf blowers, Toro makes lightweight plug-in electric models that weigh about 5 to 8 pounds. It uses line names Power Sweep, Super Blower, and Power Blower on some of its models. It also offers a line of cordless handhelds. Toro leaf blowers are among the most widely available and can be found at mass merchants, home centers, online retailers, and hardware stores. Weed Eater, now owned by Husqvarna, sells electric and gas leaf blowers. Its products are value-priced, and many are lightweight. Weed Eater leaf blowers can be found at mass merchants, online retailers, and hardware stores. (CR does not currently test Weed Eater leaf blowers.) ![]() Microsoft has announced the release of TypeScript 2.7. The new version includes stricter property checks, definite assignment assertions and easier ECMAScript module interoperability. Visual Studio Code support is expected to come soon. “We always try to bring more joy to the TypeScript experience,” said Daniel Rosenwasser, program manager for TypeScript, in a blog post. “We hope this release continues the tradition of making you more productive and expressive to bring that joy to the core experience.” InterSystems announces new data platform “InterSystems shares a commitment to innovation with our customers and partners, and we’ve developed InterSystems IRIS Data Platform to accelerate the development of new, more robust and data-rich applications,” said Paul Grabscheid, InterSystems vice president of Strategy. “InterSystems IRIS is empowering innovative organizations to become truly data driven, taking data out of stagnant silos and turning it into actionable insights that drive better business decisions and customer experiences.” WayRay announces AR SDK challenge and hackathon “The competition is the next step for WayRay towards creating a strong community of software engineers, content providers and hardware manufacturers creating AR solutions for cars,” the company said in a statement. Hortonworks updates data management solution “As more and more organizations embrace the value of capturing data in motion, they are also devising more ambitious objectives and sophisticated approaches to maximizing the utility of that data and leveraging the insights provided,” said Scott Gnau, chief technology officer at Hortonworks. “This latest release improves ease-of-use and time to value by enabling developer productivity while also expanding enterprise interoperability.” Our comprehensive testing methodology builds on CR’s expertise in testing cameras, televisions, and other connected devices. We focus our tests on how quickly a camera sends alerts to your smartphone when motion is detected—and for video doorbells, when you can see who pressed the bell—as well as its video quality, smart features, data privacy, and data security. These factors can make or break your experience with wireless security cameras and video doorbell cameras. For the response-time test, we measure how long it takes for the camera to detect movement occurring in its field of view and send alerts to its smartphone app. For video doorbells, we also time how long it takes for a button press to result in a smartphone alert and, subsequently, a live video feed, which is critical if someone is waiting at your front door. For the video-quality test, we set up a room with multiple resolution charts, everyday objects, and mannequins as stand-ins for people, and evaluate how clear the video is from cameras in good light, low light, and zero light (to test night vision). CR’s engineers designed this test to expose weak spots in the cameras, whether in their sensor, lens, or software. We also add different levels of backlighting to each lighting scenario. All these tests assess whether you would be able to clearly see people or objects in the frame, such as a potential intruder. The results of these tests appear in an individual video quality score for each wireless security camera and video doorbell in our ratings. When it comes to smart features, we assess a wide variety of capabilities, depending on the type of home security camera. They may include monitoring zones, person detection, facial recognition, voice and app control (with Amazon Alexa, Google Home/Assistant, and Apple Home/Siri), smartphone alerts, two-way audio, scheduling, and geofencing (which turns alerts on and off, depending on whether the device reads that your smartphone and you, presumably, are nearby). All these features factor into our unique Smart IQ score for smart home devices, allowing you to see which cameras are smarter than the competition. Due to repeated hacks of wireless security cameras and the growing privacy concerns about video doorbells that record audio in public areas (such as streets and sidewalks), we test all these cameras for data privacy and security. In these tests, we evaluate each company’s or service provider’s public documentation, such as privacy policies and terms of service, to see what claims the manufacturer makes about the way it handles your data. The tests include inspection of the user interface and network traffic from each camera and its companion smartphone app to make sure it’s using encryption, adhering to manufacturer policies, and not sharing your data with irrelevant third parties. Additionally, we conduct testing to see if whether can find security vulnerabilities that cybercriminals could exploit. Finally, our test engineers take the results of these individual tests and use them to calculate our Overall Scores for both wireless security cameras and video doorbell cameras. ![]() Solution providers, VARs and strategic service providers look to IT vendors to provide them with the industry-leading hardware and software products they need to meet their customers’ needs. No surprise, then, that IT vendor product portfolios are often the most important component of vendor-channel relationships. But a critical part of any solution provider decision about which IT vendors to work with is what a vendor has to offer to help partners be more successful, including margins and financial incentives, sales and marketing assistance, training and certifications, and more. When solution providers choose which IT vendors to align with, vendors’ partner programs must be a big part of that decision. To help with those evaluations, CRN assembles its annual Partner Program Guide. This year the guide is based on detailed applications submitted by more than 300 vendors, outlining all aspects of their partner programs. Vendors know they have to be at the top of their game when it comes to offering solution providers incentives, training, recurring revenue opportunities and more. Here are the vendors leading the way. We asked IT vendors to provide their “elevator pitch” to convince solution providers to join their partner program. Here’s what 25 had to say. We asked IT vendors what element of their partner program they wished more partners took advantage of and what benefits partners are leaving on the table. Here’s what 25 had to say. IT vendors were asked what they considered to be the top goals for their partner programs in 2023. Here’s what 25 had to say. Five-Star ProfilesAs part of the Partner Program Guide, CRN designates some top vendor channel programs as 5-Star Partner Programs - programs that offer the most comprehensive lineups of incentives, training, services and benefits. The following slide shows highlight the vendor programs with 5-Star recognition. We’ll be rolling out these slide shows through the week according to technology category. 5-Star Emerging Vendor Programs >>5-Star Distributor Programs >>5-Star Security Vendor Programs >>5-Star Networking and Unified Communications Vendor Programs >>5-Star Device And Peripherals Vendor Programs >>5-Star Data Storage And Backup Vendor Programs >>5-Star Software Vendor Programs >>5-Star Cloud Platform And Infrastructure Vendor Programs >>5-Star System And Data Center Vendor Programs >>Partner Program DetailsResults will be shown here Past Partner Program Guides2022 | 2021 | 2020 | 2019 | 2018 | 2017 | 2016 | 2015 | 2014 | 2013 | 2012 | 2011 See Also: 2023 Channel Chiefs

Illustration by Angela Kirkwood Buying a new HVAC system is one of the most important purchases you can make for your home. Consumer Reports indicates that more than 75% of U.S. homes use air conditioning, and 90% of new homes are equipped with central air. An efficient HVAC system offers a comfortable environment in which to work, relax and enjoy your home. How Much Does Air Duct Cleaning Cost Gathering all the correct information about HVAC systems can be intimidating. With the volume of information available online, it is natural to feel overwhelmed and confused about HVAC systems. To help, we’ve built a guide for buying HVAC systems so you make an informed buying choice. What Is an HVAC System?HVAC refers to technology that allows for regulation of a home’s atmosphere. HVAC is an abbreviation for Heating, Ventilation and Air Conditioning. HVAC systems enable occupants to have proper control over the heating and cooling temperatures of a space. They are also commonly known by the names of some common components: ductless AC units, boilers, central air conditioners, heat pumps or furnaces. Types of HVAC SystemsThere are four main types of HVAC systems: Split systems, hybrid systems, ductless systems and packaged heating and air systems. You should choose what’s most suitable for your home and budget.
HVAC System Factors to ConsiderHome Comfort: Temperature and Air QualityYou should always consider how various heating and cooling units will influence your indoor temperature, energy consumption and air quality. For example, did you know that choosing elements such as UV light in your HVAC system can increase your EPA indoor air quality score? A little inquiry will help you tackle airborne particle content and identify the best HVAC unit for reducing humidity. EfficiencyHVAC systems have improved over the years. As a result, there are rating systems that determine their efficiency. Take a look at the system ratings, such as the Seasonal Energy Efficiency Ratio (SEER), HSPF, AFUE and EER. For example, the SEER rating should be at least 15. CapacityYour new HVAC system should be able to heat and cool the space in your home effectively. The capacity of an HVAC system is measured by BTUs (British Thermal Units). Generally, the higher the BTU rating, the greater the capacity. Programmable Thermostat CompatibilityEnsure that the system you buy is compatible with a modern, programmable thermostat. This allows you to control your heating and cooling from virtually anywhere. In addition, you’ll be able to save money on your energy bills by turning the systems on or off when you are not using them. It will also prolong the life of your HVAC system. Some units can be controlled via a wire to other parts of a house, while the most modern can be controlled via smartphone from anywhere the phone receives service. Maintenance requirementsHVAC systems need regular maintenance for optimal performance, so buy a low-maintenance, cost-effective system. When you negotiate your installation, you should also negotiate a service plan that combines regular inspections with discounts on repairs and a labor warranty into the overall price. SoundDepending on the type and where it is installed, an HVAC system can be pretty noisy. Consult with your HVAC contractor to ensure the unit you choose is a good fit for your home and your noise tolerance levels. PriceWhen choosing the right HVAC system, your goal should be to provide a comfortable temperature for your home, even if it’s more expensive than others. While you should buy an HVAC unit according to your budget, consider other factors as well, such as energy efficiency and durability. The cheapest option isn’t always the best quality and rarely will be the most efficient—remember too that the money saved in energy and repair costs, by purchasing the correct size and a better quality unit, should weigh into any buying decision. HVAC System Costs by TypeThe average cost is dependent on the brand purchased, the size of a home and the HVAC installation cost charged by the contractor. An HVAC is a complicated system made up of many different parts. You might be making a complete replacement or just getting a new piece for your existing unit. In any case, it helps to know the system cost for several parts. A central air conditioner works to keep your whole home cool by circulating air over refrigerated coils. The cost to install an air conditioner runs roughly between $3,350 and $5,950. On the other hand, a heat pump transfers air from a cooler area to a warmer area using thermal energy. A conventional heat pump will cost you around $4,000 to $8,000, while a geothermal pump can be about five times that price, about $15,000 to $35,000. A furnace is a heating system that uses some sort of fuel to heat an entire building. A gas furnace will cost an average of $1,800 to $4,000, an oil furnace between $4,200 and $6,900 while an electric furnace ranges from $1,600 to $2,500. On the other hand, a boiler works to heat a home using hot water forced through pipes. It costs an average $1,500 to $3,500. How to Choose the Right HVAC System for YouSize SystemBe sure to purchase the right size system for your home. Older homes may not have the correct size system. Oversized equipment cycles too frequently, shortening its life. Also, it won’t provide the same level of comfort and indoor air quality as a correctly sized system. Your contractor or HVAC technician should tell you what size system your home needs, as the calculations required often involve a multitude of factors including tree coverage, sun exposure and insulation in addition to square-footage and ceiling height. High-EfficiencyBuy the highest efficiency HVAC equipment you can afford that will work with your home. Even though a standard-efficiency system and a high-efficiency system might have the same labor component, the high efficiency will prove more cost-effective in the long run. ContractorChoosing the best HVAC contractor is a very crucial factor affecting the quality of the system. An HVAC system must be designed, customized and fabricated for each home. A good HVAC contractor will evaluate your entire system, including ductwork and indoor air quality requirements. They will cater to your individual needs and make recommendations that will best suit you, your home and your lifestyle. Make sure your contractor is properly licensed in their field. Ensure you sign a consumer contract for home improvements. Your agreement should include both start and completion dates and include an agreement for who pays for what, should the contract go over-bid. Indoor Air Quality (IAQ) componentsIAQ components like humidifiers and high-efficiency air filtration systems are common add-ons to HVAC systems. Most contractors will discount these additional items when installing a new system. Ask about add-ons from your contractor. WarrantiesSpend some time comparing manufacturers’ and contractors’ warranties. A warranty can save you a lot of time and headache when things break. Oftentimes, at least some parts and repairs are covered with a default warranty when buying new. If flipping a home or planning to sell a home or space, be sure to buy warranties that are transferable. Students pay nothing up front, but most will need to take out loans to cover tuition and living costs, here we offer a definitive guide to student finance. University is expensive. Students from England pay tuition fees of £9,250 per year of study, or £27,750 for a typical three-year degree. You will also have to cover living costs and rent if you live away from home, so the total cost for a degree may come in at around £60,000. How on earth can anyone afford this, you may wonder. That's where loans and grants come in. Here's everything you need to know about student finance. | ||||||||
