Review request for hive and Ashutosh Chauhan.


Repository: hive-git


Description
-------

in ql/src/java/org/apache/hadoop/hive/ql/ppd/OpProcFactory.java, line 477, when aliases contains
empty string "" and key is an empty string "" too, it assumes that aliases contains key. This
will trigger incorrect PPD. To reproduce it, apply the HIVE-10455 and run cbo_subq_notin.q.
