Review request for hive and Ashutosh Chauhan.
Bugs: HIVE-16838
https://issues.apache.org/jira/browse/HIVE-16838
Repository: hive-git
Description
-------
This patch improves plans for subqueries which have not equal corelated
predicates.
Currently to retrieve all possible correlated predicates inner table is joined
with outer query. This is un-necessary in most of the cases (exception is if
subquery has an aggregate).
