> Sometimes the test fails with the following error:
> testAMRMUnusableNodes(org.apache.hadoop.yarn.server.resourcemanager.applicationsmanager.TestAMRMRPCNodeUpdates)
> Time elapsed: 41.73 sec <<< FAILURE!
> junit.framework.AssertionFailedError: AppAttempt state is not correct
> (timedout) expected:<ALLOCATED> but was:<SCHEDULED>
> at junit.framework.Assert.fail(Assert.java:50)
> at junit.framework.Assert.failNotEquals(Assert.java:287)

> When this happens, SchedulerEventType.NODE_UPDATE was processed before
> RMAppAttemptEvent.ATTEMPT_ADDED was processed. That is possible, given the
> test only waits for RMAppState.ACCEPTED before having NM sending heartbeat.
> This can be reproduced using custom AsyncDispatcher with CountDownLatch. Here
> is the log when this happens.
