> 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.
