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
* 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 pair in the grouped inputs.
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?
A. Oozie
B. Sqoop
C. Flume
D. Hadoop Streaming
E. mapred
Answer: D
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: (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.
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
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
For each map instance that runs, the TaskTracker creates a new instance of your
* 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 {
while (context.nextKeyValue()) {
map(context.getCurrentKey(), context.getCurrentValue(), context);
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.
Question: 102
Which one of the following files is required in every Oozie Workflow application?
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?
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
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
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?
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?

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
Answer: D
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
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.

Home Security Camera Buying Guide

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.

2023 Partner Program Guide

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 Profiles

As 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.

Best HVAC System Buying Guide: How To Choose The Best One For You

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 Systems

There 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.

  • Split system: “Split” between two main units or systems (one for cooling and one for heating), most common among the HVAC systems
  • Hybrid system: Advanced version of the split system, main difference is that it has improved energy efficiency as it is equipped with a hybrid electric heater system
  • Ductless system: consists of an outside air conditioner for cooling and a heat pump for cooling and heating, suitable for homes where conventional systems of ducts cannot be used
  • Packaged system: offers high-quality heating and cooling combined into one unit, usually used in homes without basements and is usually installed outdoors

HVAC System Factors to Consider

Home Comfort: Temperature and Air Quality

You 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.


HVAC 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.


Your 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 Compatibility

Ensure 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 requirements

HVAC 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.


Depending 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.


When 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 Type

The 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 You

Size System

Be 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.


Buy 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.


Choosing 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) components

IAQ 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.


Spend some time comparing manufacturers’ and contractors’ warranties. A warranty can save you a lot of time and headache when things break.
