Description

It appears the second column is getting truncated. This doesn't happen when performing other join types:

impala-shell -i localhost -q "use functional_text_lzo; select j.*, d.* from JoinTbl j full outer join DimTbl d on (j.test_id=d.id) where j.test_id=1001
1001	e1	94611	5000	1001	Name1	94611

impala-shell -i localhost -q "use functional_seq_snap; select j.*, d.* from JoinTbl j full outer join DimTbl d on (j.test_id=d.id) where j.test_id=1001
1001	Name1	94611	5000	1001	Name1	94611
