Nice work. I left a couple of minor comments on RB.

> Key: HIVE-8276
> URL: https://issues.apache.org/jira/browse/HIVE-8276
> Project: Hive
> Issue Type: Sub-task
> Components: Spark
> Reporter: Xuefu Zhang

> 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.
