Subject [jira] [Created] (HIVE-3225) NPE on a join query with authorization enabled

---------------------------------

             Summary: NPE on a join query with authorization enabled
                 Key: HIVE-3225
                 URL: https://issues.apache.org/jira/browse/HIVE-3225
             Project: Hive
          Issue Type: Bug
          Components: Security
    Affects Versions: 0.9.0
            Reporter: Francis Liu
            Assignee: Francis Liu


when performing a join query which filters by a non-existent partition in the where clause
(ie):

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.
