             Summary: TestAdmissionController.test_release_backend is flaky

                 URL: https://issues.apache.org/jira/browse/IMPALA-8989
             Project: IMPALA
          Issue Type: Bug

    Affects Versions: Impala 3.4.0

Test seems to have failed due to a mismatch in number of completed backend. Only failed once so far.
