Aihua Xu updated HIVE-13855:
----------------------------
Status: Patch Available (was: Open)
patch-1: process no plan case rather than throwing NPE. Since such query throws
the NPE exception but such exception is caught outside, the query will succeed.
We already have test case cover it, so I didn't add test case. It's better not
to throw and log such NPE for a valid case.
> select INPUT__FILE__NAME throws NPE exception
