Subject [jira] [Created] (YARN-6813) TestAMRMProxy#testE2ETokenRenewal fails sporadically due to race conditions

Jason Lowe created YARN-6813:
--------------------------------

             Summary: TestAMRMProxy#testE2ETokenRenewal fails sporadically due to race conditions
                 Key: YARN-6813
                 URL: https://issues.apache.org/jira/browse/YARN-6813
             Project: Hadoop YARN
          Issue Type: Bug
          Components: test
    Affects Versions: 2.8.1
            Reporter: Jason Lowe


The testE2ETokenRenewal test lowers the AM and nodemanager heartbeat intervals to only 1.5
seconds.  This leaves very little headroom over the default heartbeat intervals of 1 second.
If the AM hits a hiccup and runs a bit slower than expected the unit test can fail because
the RM expires the AM.
