Hortonworks-Certified-Apache-Hadoop-2.0-Developer(Pig and Hive Developer) Sample Questions:

Question #1
In Hadoop 2.0, which one of the following statements is true about a standby NameNode?
The Standby NameNode:

A. Processes all client requests and block reports from the appropriate DataNodes.
B. Runs on the same machine and shares the memory of the active NameNode.
C. Communicates directly with the active NameNode to maintain the state of the active NameNode.
D. Receives the same block reports as the active NameNode.

Question #2
You wrote a map function that throws a runtime exception when it encounters a control character in input
data. The input supplied to your mapper contains twelve such characters totals, spread across five file
splits. The first four file splits each have two control characters and the last split has four control
characters.
Indentify the number of failed task attempts you can expect when you run the job with
mapred.max.map.attempts set to 4:

A. You will have forty-eight failed task attempts
B. You will have twelve failed task attempts
C. You will have seventeen failed task attempts
D. You will have five failed task attempts
E. You will have twenty failed task attempts

Question #3
You are developing a combiner that takes as input Text keys, IntWritable values, and emits Text keys,
IntWritable values. Which interface should your class implement?

A. Reducer <Text, Text, IntWritable, IntWritable>
B. Reducer <Text, IntWritable, Text, IntWritable>
C. Combiner <Text, Text, IntWritable, IntWritable>
D. Mapper <Text, IntWritable, Text, IntWritable>
E. Combiner <Text, IntWritable, Text, IntWritable>

Question #4
Determine which best describes when the reduce method is first called in a MapReduce job?

A. Reduce methods and map methods all start at the beginning of a job, in order to provide optimal
performance for map-only or reduce-only jobs.
B. Reducers start copying intermediate key-value pairs from each Mapper as soon as it has completed.
The reduce method is called only after all intermediate data has been copied and sorted.
C. Reducers start copying intermediate key-value pairs from each Mapper as soon as it has completed.
The programmer can configure in the job what percentage of the intermediate data should arrive before
the reduce method begins.
D. Reducers start copying intermediate key-value pairs from each Mapper as soon as it has completed.
The reduce method is called as soon as the intermediate key-value pairs start to arrive.

Question #5
In a MapReduce job, the reducer receives all values associated with same key. Which statement best
describes the ordering of these values?

A. The values are in sorted order.
B. Since the values come from mapper outputs, the reducers will receive contiguous sections of sorted
values.
C. The values are arbitrarily ordered, and the ordering may vary from run to run of the same MapReduce
job.
D. The values are arbitrary ordered, but multiple runs of the same MapReduce job will always have the
same ordering.
