             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.
