B) Text analysis algorithms on large collections of unstructured text (e.g., Web crawls).
C) Relational operations on large amounts of structured and semi structured data.
D) Algorithms that requite global, shared state.
E) Large-scale graph algorithms that require one-step link traversal.

2. Which happens if the NameNode crashes?

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

3. If you run the word count MapReduce program with m mappers and r reducers, how many output files will you get at the end of the job? And how many key-value pairs will there be in each file? Assume k is the number of unique words in the input files.

A) There will be r files, each with approximately k/r key-value pairs.
B) There will be r files, each with approximately k/m key-value pairs.
C) There will be r files, each with exactly k/r key-value pairs.
D) There will be m files, each with exactly k/m key value pairs.
E) There will be m files, each with approximately k/m key-value pairs.

4. How does the NameNode detect that a DataNode has failed?

A) When the NameNode fails to receive periodic heartbeats from the DataNode, it considers the DataNode as failed.
B) The NameNode does not need to know that a DataNode has failed.
C) The NameNode periodically pings the datanode. If the DataNode does not respond, the NameNode considers the DataNode as failed.
D) When HDFS starts up, the NameNode tries to communicate with the DataNode and considers the DataNode as failed if it does not respond.

5. To process input key-value pairs, your mapper needs to load a 512 MB data file in memory. What is the best way to accomplish this?

A) Place the datafile in the DataCache and read the data into memory in the configure method ofthe mapper.
B) Serialize the data file, insert it in the Jobconf object, and read the data into memory in the configure method of the mapper.
C) Place the data file in theDistributedCacheand read the data into memory in the configure method of the mapper.
D) Place the data file in theDistributedCacheand read the data into memory in the map method of the mapper.
