Gunther Hagleitner commented on HIVE-12573:
-------------------------------------------

I don't believe the effect is only cosmetic. Having an un-executable synthetic 
predicate left over in the TS operator breaks anyone trying to implement filter 
pushdown. However, this was introduced by HIVE-12462, which I don't think is 
the right fix in the first place. Makes sense to find out what's happening 
there before proceeding with this.
