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

             Summary: A binary eval for column references of the same tables 
should not be recognized as a join condition
                 Key: TAJO-1009
                 URL: https://issues.apache.org/jira/browse/TAJO-1009
             Project: Tajo
          Issue Type: Bug
          Components: planner/optimizer
            Reporter: Hyunsik Choi
            Assignee: Hyunsik Choi
            Priority: Trivial
             Fix For: 0.9.0


See the following example:

{code}
SELECT a,b,c from table1 where table1.a > table1.b;
{code}

EvalTreeUtil.isJoinQual recognizes the above predicate as a join qual. It's 
wrong.
