---------------------------------

             Summary: Same constants in groupby clause may cause planning error.
                 Key: TAJO-829
                 URL: https://issues.apache.org/jira/browse/TAJO-829
             Project: Tajo
          Issue Type: Bug
          Components: planner/optimizer
            Reporter: Hyunsik Choi
            Assignee: Hyunsik Choi
             Fix For: 0.9.0, 0.8.1


{code}
select l_partkey as a, '##' as b, '##' as c, count(*) d
from lineitem
group by a, b, c
{code}

See the above query case. This query causes the planning error. This patch 
fixes the bug. Also, this patch removes duplicated group by keys.

I verified 'mvn clean install'.
