A. One intermediate key-value pair, of a different type.
B. As many intermediate key-value pairs as designed, but they cannot be of the same type as the

Explanation:
Mapper maps input key/value pairs to a set of intermediate key/value pairs.
Maps are the individual tasks that transform input records into intermediate records. The
transformed intermediate records do not need to be of the same type as the input records. A given
input pair may map to zero or many output pairs.
Reference: Hadoop Map-Reduce Tutorial

NO.4 You have just executed a MapReduce job.
Where is intermediate data written to after being emitted from the Mapper's map method?
A. Into in-memory buffers on the TaskTracker node running the Reducer that spill over and are
written into HDFS.
B. Into in-memory buffers that spill over to the local file system (outside HDFS) of the TaskTracker
node running the Reducer
C. Into in-memory buffers on the TaskTracker node running the Mapper that spill over and are
written into HDFS.
D. Intermediate data in streamed across the network from Mapper to the Reduce and is never
written to disk.
E. Into in-memory buffers that spill over to the local file system of the TaskTracker node running the
Mapper.
Answer: E
Explanation:
The mapper output (intermediate data) is stored on the Local file system (NOT HDFS) of each
individual mapper nodes. This is typically a temporary directory location which can be setup in config
by the hadoop administrator. The intermediate data is cleaned up after the Hadoop Job completes.
