Prasanth Jayachandran commented on HIVE-9512:
---------------------------------------------

[~jcamachorodriguez] The union issue was already known. I have a TODO in StatsRulesProcFactory
which says union queries have issue with propagating the aliases. It seems to work now. Thats
a good thing. But I am concerned about the UDF, UDAF which seems to cause regression.
