sandflee commented on YARN-5023:
--------------------------------

{code}
    // launch next AM in nm2
    nm2.nodeHeartbeat(true);
    MockAM am5 =
        rm1.waitForNewAMToLaunchAndRegister(app1.getApplicationId(), 5, nm2);
{code}
seems we should not send nodeHeartBeat, since NODE STATUS_UPDATE event is processed async, there could be race conditions than app attempt becomes ALLOCATED but we are waiting for SCHEDULED.
[~bibinchundatt] if you had not worked on this, I'd like update a patch.
