>             Project: Hive
>          Issue Type: Bug
>    Affects Versions: 2.1.0
>            Reporter: Teruyoshi Zenmyo
>
> With predicate pushdown enabled, NOT IN conditions are treated as FALSE.
> Example (pkey is a partition key)
> {code}
> hive> select * from test;
> OK
> test.key        test.val        test.pkey
> a       1       a
> b       2       a
> c       3       a
> a       1       b
> b       2       b
> c       3       b
> Time taken: 0.171 seconds, Fetched: 6 row(s)
> hive> set hive.optimize.ppd=false;
> hive> select * from test where not pkey in ('a');
> OK
> test.key        test.val        test.pkey
> a       1       b
> b       2       b
> c       3       b
> Time taken: 0.237 seconds, Fetched: 3 row(s)
> hive> set hive.optimize.ppd=true;
