Review request for hive and Xuefu Zhang.
Bugs: HIVE-10844
https://issues.apache.org/jira/browse/HIVE-10844
Repository: hive-git
Description
-------
Some Hive queries(like TPCDS Q39) 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.
