Cloudera CCD-333 Exam Syllabus Topics:

Cloudera Certified Developer for Apache Hadoop Sample Questions:

1. Which MapReduce daemon runs on each slave node and participates in job execution?

A) TaskTracker
B) Secondary NameNode
C) JobTracker
D) NameNode

2. Which happens if the NameNode crashes?

A) HDFS becomes temporarily unavailable until an administrator starts redirecting client requests to the Secondary NameNode.
B) The Secondary NameNode seamlessly takes over and there is no service interruption.
C) HDFS becomes unavailable to new MapReduce jobs, but running jobs will continue until completion.
D) HDFS becomes unavailable until the NameNode is restored.

3. You have written a Mapper which invokes the following five calls to the outputcollector.collect method:

How many times will the Reducer's reduce method be invoked.

A) 0
B) 1
C) 6
D) 5
E) 3

4. You have the following key value pairs as output from your Map task:
(The, 1)
(Fox, 1)
(Runs, 1)
(Faster, 1)
(Than, 1)
(The, 1)
(Dog, 1)
How many keys will be passed to the reducer?

A) Two
B) Six
C) Three
D) Five
E) One
F) Four

5. You write a MapReduce job to process 100 files in HDFS. Your MapReduce algorithm uses TextInputFormat and the IdentityReducer: the mapper applies a regular expression over input values and emits key-value 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 reducers to zero.

A) 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.
B) There is no difference in output between the two settings.
C) With zero reducers, all instances of matching patterns are gathered together in one file on HDFS. With one reducer, instances of matching patterns 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.
