>             Project: Pig
>          Issue Type: Bug
>          Components: impl
>    Affects Versions: 0.8.0

> The following script produce wrong result:
> test1.dat:
> 1
> 2
> 3
> test2.dat:
> 1
> 2
> pig script:
> {code}
> a = LOAD 'test1.dat' USING PigStorage() AS (d1:int);
> b = LOAD 'test2.dat' USING PigStorage() AS (d2:int);
> c = JOIN a BY d1 FULL OUTER, b BY d2;
> d = FILTER c BY d2 IS NULL;
> STORE d INTO 'test.out' USING PigStorage();
> {code}
> expected:
> 3
> We get:
> 1
> 2
> 3
> This is because we erroneously push the filter before full outer join. Similar issue
is addressed in [PIG-1289|https://issues.apache.org/jira/browse/PIG-1289], but we only fix
left/right outer join.
