(Updated June 23, 2015, 7:24 a.m.)


Review request for hive and Xuefu Zhang.


Changes
-------

fix Xuefu's second round comments.


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.
