Rohith Sharma K S commented on YARN-4615:
-----------------------------------------
Analysis make sense to me, I am able to reproduce the issue keeping very small
delay like below
{code}
node.nodeHeartbeat(applicationAttemptOneID, 1, ContainerState.COMPLETE);
Thread.sleep(200);
rm.waitForState(node, am1ContainerID, RMContainerState.COMPLETED);
{code}
About the patch, would you use existing method
{{MockRM#waitForContainerState(ContainerId containerId,RMContainerState
state)}} and modify a little bit for incorporating your new method logic.
For testing purpose, you can use small delay like in the above.
