B) Hue
C) Hive
D) Sqoop
E) HBase
F) Flume
G) Oozie

2. In the standard word count MapReduce algorithm, why might using a combiner reduce the overall Job running time?

C) Because combiners perform local aggregation of word counts, and then transfer that data to reducers without writing the intermediate data to disk.
D) 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.
