Cloudera Certified Developer for Apache Hadoop Sample Questions:

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

A) 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.
B) The file is replicated three times by default. Eachcopy of the file is stored on a separate datanodes.
C) 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.
D) The file is divided into variable size blocks, which are stored on multiple data nodes. Each block is replicated three times by default.
E) 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.

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

A) 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.
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) Setting the number of reducers to one is invalid, and an exception is thrown.
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.

3. What is the behavior of the default partitioner?

A) The default partitioner assigns key value pairs to reducers based on an internal random number generator.
B) The default partitioner computes the hash of the key. Hash values between specific ranges are associated with different buckets, and each bucket is assigned to a specific reducer.
C) The default partitioner computes the hash of the value and takes the mod of that value with the number of reducers. The result determines the reducer assigned to process the key value pair.
D) The default partitioner implements a round robin strategy, shuffling the key value pairs to each reducer in turn. This ensures an even partition of the key space.
E) The default partitioner computes the hash of the key and divides that value modulo the number of reducers. The result determines the reducer assigned to process the key-value pair.

4. Your Custer's HOFS block size is 64MB. You have a directory containing 100 plain text files, each of which Is 100MB in size. The InputFormat for your job is TextInputFormat. How many Mappers will run?

A) 64
B) 640
C) 100
D) 200

5. What is a SequenceFile?

A) A SequenceFile contains a binary encoding of an arbitrary number of WritableComparable objects, in sorted order.
B) A SequenceFile contains a binary encoding of an arbitrary number key-value pairs. Each key must be the same type. Each value must be same type.
C) A SequenceFile contains a binary encoding of an arbitrary number of homogeneous writable objects.
D) A SequenceFile contains a binary encoding of an arbitrary number of heterogeneous writable objects.
