Gunther Hagleitner commented on HIVE-12473:
-------------------------------------------
I can't figure out why this fix would be doing the right thing. The converter
should work off of the final type, it needs to convert the string partition
value to the output of the evaluator. I think this should be reverted.
> DPP: UDFs on the partition column side does not evaluate correctly

> Ends up being evaluated as {{year(cast(dt as int))}} because the pruner only
