------------------------------
Summary: DummyTable map joins mix up columns between tables
Key: HIVE-13191
URL: https://issues.apache.org/jira/browse/HIVE-13191
Project: Hive
Issue Type: Bug
Affects Versions: 2.0.0, 2.1.0
Reporter: Gopal V
{code}
SELECT
a.key,
a.a_one,
b.b_one,
a.a_zero,
b.b_zero
FROM
(
SELECT
11 key,
0 confuse_you,
1 a_one,
0 a_zero
) a
LEFT JOIN
(
SELECT
11 key,
0 confuse_you,
1 b_one,
0 b_zero
) b
ON a.key = b.key
;
11 1 0 0 1
{code}
This should be 11, 1, 1, 0, 0 instead.
Disabling map-joins & using shuffle-joins returns the right result.
