Ashutosh Chauhan commented on HIVE-16293:
-----------------------------------------
Instead of creating cast only on column stats branch, this cast should be
earlier in plan for both branches. Infact, CBO should already casts in such
cases. Why is that cast not there already?
> Column pruner should continue to work when SEL has more than 1 child
