             Summary: PlannerUtil::joinJoinKeyForEachTable need to handle 
theta-join.
                 Key: TAJO-795
                 URL: https://issues.apache.org/jira/browse/TAJO-795
             Project: Tajo
          Issue Type: Bug
          Components: planner/optimizer
    Affects Versions: 0.8.0
            Reporter: Jaehwa Jung
            Assignee: Jaehwa Jung


Currently, Tajo supports only equi-join, thus shuffle keys have to include 
equi-jon conditions. But it includes theta-join conditions occasionally. We 
need to update this bug, because tajo may be returned wrong row numbers. 
Actually, I found that TPC-DS Q32 had returned unexpected results by this bug.
