Cloudera Certified Developer for Apache Hadoop Sample Questions:

1. Your client application submits a MapReduce job to your Hadoop cluster. The Hadoop framework looks for an available slot to schedule the MapReduce operations on which of the following Hadoop computing daemons?

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

2. Which of the following statements best describes how a large (100 GB) file is stored in HDFS?

A) The file is replicated three times by default. Eachcopy of the file is stored on a separate datanodes.
B) The master copy of the file is stored on a single datanode. The replica copies are divided into fixed-size blocks, which are stored on multiple datanodes.
C) The file is divided into fixed-size blocks, which are stored on multiple datanodes. Each block is replicated three times by default. Multiple blocks from the same file might reside on the same datanode.
D) The file is divided into fixed-size blocks, which are stored on multiple datanodes. Each block is replicated three times by default.HDFS guarantees that different blocks from the same file are never on the same datanode.
E) The file is divided into variable size blocks, which are stored on multiple data nodes. Each block is replicated three times by default.

3. What happens in a MapReduce job when you set the number of reducers to one?

A) Setting the number of reducers to one is invalid, and an exception is thrown.
B) A single reducer gathers and processes all the output from all the mappers. The output is written to a single file in HDFS.
C) A single reducer gathers and processes all the output from all the mappers. The output is written in as many separate files as there are mappers.
D) Setting the number of reducers to one creates a processing bottleneck, and since the number of reducers as specified by the programmer is used as a reference value only, the MapReduce runtime provides a default setting for the number of reducers.

4. What is the difference between a failed task attempt and a killed task attempt?

A) A failed task attempt is a task attempt that did not generate any key value pairs. A killed task attempt is a task attempt that threw an exception, and thus killed by the execution framework.
B) A failed task attempt is a task attempt that completed, but with an unexpected status value. A killed task attempt is a duplicate copy of a task attempt that was started as part of speculative execution.
C) A failed task attempt is a task attempt that threw an unhandled exception. A killed task attempt is one that was terminated by the JobTracker.
D) A failed task attempt is a task attempt that threw a RuntimeException (i.e., the task fails). A killed task attempt is a task attempt that threw any other type of exception (e.g., IOException); the execution framework catches these exceptions and reports them as killed.

5. What types of algorithms are difficult to express MapReduce?

A) Large-scale graph algorithms that require one-step link traversal.
B) Algorithms that requite global, shared state.
C) Relational operations on large amounts of structured and semi structured data.
D) Algorithms that require applying the same mathematical function to large numbers of individual binary records.
E) Text analysis algorithms on large collections of unstructured text (e.g., Web crawls).
