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

             Summary: Combine equivalent Works for HoS[Spark Branch]
                 Key: HIVE-10844
                 URL: https://issues.apache.org/jira/browse/HIVE-10844
             Project: Hive
          Issue Type: Sub-task
          Components: Spark
            Reporter: Chengxiang Li
            Assignee: Chengxiang Li


Some Hive queries(like [TPCDS Q39|https://github.com/hortonworks/hive-testbench/blob/hive14/sample-queries-tpcds/query39.sql])
may share the same subquery, which translated into sperate, but equivalent Works in SparkWork,
combining these equivalent Works into a single one would help to benifit from following dynamic
RDD caching optimization.
