Sushanth Sowmyan commented on HIVE-6724:
----------------------------------------
Committed to trunk. Thanks, Eugene.
Also, re-setting fix version as 0.14, as fix version tracks the version the
patch has already been committed to. [~rhbutani] will be the one to backport to
0.13 after he's satisfied with it, and he can set it to 0.13.
