Review request for hive and Xuefu Zhang.

Bugs: HIVE-8276

Repository: hive-git


Currently ShuffleTran captures both shuffle and reduce side processing. Per HIVE-8118, sometimes
the output RDD from shuffle needs to be cached for better performance. Thus, it makes sense
to separate shuffle from Reduce and create ShuffleTran class.
