[jira] [Created] (IMPALA-5956) Read-only query returns varying results when run repeatedly

Tim Wood created IMPALA-5956:
--------------------------------

             Summary: Read-only query returns varying results when run repeatedly
                 Key: IMPALA-5956
                 URL: https://issues.apache.org/jira/browse/IMPALA-5956
             Project: IMPALA
          Issue Type: Bug
            Reporter: Tim Wood
         Attachments: q89-flap1.out, q89-flap2.out

When run esp. as part of the TPC-DS suite, query #89 returns varying results in the LSD of a calculation.  Using the output of the previous run as the expected result for the next run fails. This SELECT item is a ROUND() expression, so it's not clear why the result is not deterministic.
