Jesus Camacho Rodriguez updated HIVE-10785:
-------------------------------------------
Description: Enable {{AggregateJoinTransposeRule}} in CBO that pushes
Aggregate through Join operators. The rule needs to be extended to cover other
cases e.g. Aggregate operators comprising UDAF. The decision on whether to push
the Aggregate through Join or not should be cost-driven. (was: Enable
{{AggregateJoinTransposeRule}} in CBO that pushes Aggregate through Join
operators (if possible).)
> Support aggregate push down through joins
