NO.1 For each input key-value pair, mappers can emit:
A. As many intermediate key-value pairs as designed. There are no restrictions on the types of those
key-value pairs (i.e., they can be heterogeneous).
B. As many intermediate key-value pairs as designed, as long as all the keys have the same types and
all the values have the same type.
C. One intermediate key-value pair, of a different type.
D. One intermediate key-value pair, but of the same type.

input key-value pair.
Answer: B
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.
