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

             Summary: test_last_ddl_time_update fails on S3
                 Key: IMPALA-6124
                 URL: https://issues.apache.org/jira/browse/IMPALA-6124
             Project: IMPALA
          Issue Type: Bug
          Components: Infrastructure
    Affects Versions: Impala 2.11.0
            Reporter: Lars Volker
            Priority: Blocker


This looks like the test took longer than 20s and thus failed. I don't understand why the two timestamps should be within 20s. My suggestion would be to change the check to something like this:

{code:python}
assert long(afterDdlTime) - long(beforeDdlTime) > 0
{code}

[~alex.behm] - You wrote the original code. Do you remember why we perform this check? If you agree with the change I suggested, I'll go ahead and prepare a patch.
