---------------------------------

             Summary: Separate shuffle from ReduceTran and so create ShuffleTran [Spark Branch]
                 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.
