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

             Summary: TestFetch.test_client_fetch_time_stats_incomplete is flaky
                 Key: IMPALA-12201
                 URL: https://issues.apache.org/jira/browse/IMPALA-12201
             Project: IMPALA
          Issue Type: Bug
          Components: Backend, Infrastructure
    Affects Versions: Impala 4.3.0
            Reporter: Joe McDonnell


Test runs have been this test failure for TestFetch.test_client_fetch_time_stats_incomplete:
{noformat}
query_test/test_fetch.py:133: in test_client_fetch_time_stats_incomplete
    assert summary_stats[0].total_num_values == 6
E   assert 5 == 6
E    +  where 5 = TSummaryStatsCounter(total_num_values=5, name=None, max_value=2602000000.0, sum=3007975000.0, min_value=100999000.0, unit=None).total_num_values{noformat}
We expect there to be 6 time periods for the ClientFetchWaitTimeStats (the time before each of the 5 fetches plus a final period). This has been seen once so far.
