                 Key: HIVE-21768
                 URL: https://issues.apache.org/jira/browse/HIVE-21768
             Project: Hive
          Issue Type: Bug
          Components: Logical Optimizer
    Affects Versions: 3.1.1, 4.0.0
            Reporter: Gopal V


{code}
beeline> select 1  union all select 2;

+----------+
| _u1._c0  |
+----------+
| 2        |
| 1        |
+----------+
{code}

The _u1 is superfluous and harmful to result schema parsing.
