Review request for hive and Xuefu Zhang.
Changes
-------
Addressing comments. Thanks Xuefu!
Bugs: HIVE-8276
https://issues.apache.org/jira/browse/HIVE-8276
Repository: hive-git
Description
-------
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.
