for some reason phabricator didn't update the jira:

>                 URL:
>             Project: Hive
>          Issue Type: Bug

> when performing a join query which filters by a non-existent partition in the where clause
> select t1.a as a1, t2.a as a2 from t1 join t2 on t1.a=t2.a where t2.part="non-existent";
> It returns an NPE. It seems that the partition since non-existent is not part of the
list of inputs (or maybe optimized out?). But the TableScanOperator still has a reference
to it which causes an NPE after tableUsePartLevelAuth.get() returns null.
