Gunther Hagleitner commented on HIVE-4260:
------------------------------------------
Mapjoin hints are specifically disallowed before and after unions (per comments
in the code). The same queries work with auto join convert and no hint. I've
rewritten the tests accordingly.
> union_remove_12, union_remove_13 are failing on hadoop2
