Jacques Nadeau created DRILL-4521:
-------------------------------------

             Summary: Drill doesn't correctly treat VARIANCE and STDDEV as two phase aggregates
                 Key: DRILL-4521
                 URL: https://issues.apache.org/jira/browse/DRILL-4521
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Jacques Nadeau
            Assignee: MinJi Kim


These are supposed to be synonyms with STDDEV_POP and VARIANCE_POP but they are handled differently.
This causes the reduce aggregates rule to not reduce these and thus they are handled as single
phase aggregates.
