You've written a MapReduce job that will process 500 million input records and generate 500 million key-value pairs. The data is not uniformly distributed. Your MapReduce job will create a significant amount of intermediate data that it needs to transfer between mappers and reducers which is a potential bottleneck. A custom implementation of which of the following interfaces is most likely to reduce the amount of intermediate data transferred across the network?
- A. Combiner
- B. Partitioner
- C. Writable
- D. WritableComparable
- E. InputFormat
- F. OutputFormat

Which of the following statements best describes how a large (100 GB) file is stored in HDFS?
- A. 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.
- B. 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.
- C. The file is divided into variable size blocks, which are stored on multiple data nodes. Each block is replicated three times by default.
- D. The file is replicated three times by default. Eachcopy of the file is stored on a separate datanodes.
- E. 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.

In a large MapReduce job with m mappers and r reducers, how many distinct copy operations will there be in the sort/shuffle phase?
- A. mr (i.e., m to the power of r)
- B. m
- C. m+r (i.e., m plus r)
- D. mxr (i.e., m multiplied by r)
- E. r

In the standard word count MapReduce algorithm, why might using a combiner reduce the overall Job running time?
- A. Because combiners perform local aggregation of word counts, and then transfer that data to reducers without writing the intermediate data to disk.
- B. Because combiners perform local aggregation of word counts, thereby reducing the number of key-value pairs that need to be snuff let across the network to the reducers.
- C. Because combiners perform local aggregation of word counts, thereby reducing the number of mappers that need to run.
- D. Because combiners perform local aggregation of word counts, thereby allowing the mappers to process input data faster.
