[jira] [Commented] (YARN-5700)
testAMRestartNotLostContainerCompleteMsg times out intermittently in 2.8
[ https://issues.apache.org/jira/browse/YARN-5700?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15542824#comment-15542824 ]
Eric Badger commented on YARN-5700:
-----------------------------------
testAMRestartNotLostContainerCompleteMsg times out intermittently in branch-2.8, but also intermittently increases the runtime of the test in branch-2 and trunk by ~10 seconds. These phenomena can be reproduced reliably by adding a {{Thread.sleep(10)}} to the code as shown below. A sleep as low as 1ms seems to trigger the race condition, though it isn't 100% reliable for failure at a sleep value that low.

771 // container complete
772 nm1.nodeHeartbeat(
773 am1.getApplicationAttemptId(), 2, ContainerState.COMPLETE);
774 Thread.sleep(10);
775 rm1.waitForState(nm1, containerId2, RMContainerState.COMPLETED);
