             Summary: custom_cluster.test_breakpad.TestLogging.test_excessive_cerr_ignore_pid seems to be flaky
                 Key: IMPALA-14182
                 URL: https://issues.apache.org/jira/browse/IMPALA-14182
             Project: IMPALA
          Issue Type: Bug
            Reporter: Fang-Yu Rao
            Assignee: Joe McDonnell


We found that {{test_excessive_cerr_ignore_pid()}} in [https://github.com/apache/impala/blob/master/tests/custom_cluster/test_breakpad.py] could fail with the following error message and stack trace. It looks like we could have more log files (5) than expected (4).
