Sunil G commented on YARN-5023:
-------------------------------
Yes [~sandflee]. I was also trying to mention the same, sorry for lack of
clarity earlier. Two node heartbeats caused the issue. And as you suggested, we
can remove the first one from test case, as its been invoked from {{launchAM}}
internally also.
I am not seeing any point in sending heartbeat explicitly from test case. As
[~rohithsharma] and me explained in YARN-4478 summary, we have seen many cases
where contributers used apis from MockRM without knowing nodeHeartBeat is sent
internally. And this is good example for same. :)
