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

             Summary: Scalar replacement bug with Common Subexpression Elimination
                 Key: DRILL-3995
                 URL: https://issues.apache.org/jira/browse/DRILL-3995
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Steven Phillips


The following query:
 {code}
select t1.full_name from cp.`employee.json` t1, cp.`department.json` t2 where t1.department_id
= t2.department_id and t1.position_id = t2.department_id
{code}

fails with the following:
