Xuan Gong commented on YARN-5029:
---------------------------------

Thanks for the review. Junping.

Uploaded a new patch to fix checkstyle issue and testcase failure.

bq. TestSystemMetricsPublisher to check if SystemMetricsPublisher received the 
event. It would be helpful to have an additional check in ATS side to actually 
see event is written in backend - just like what we have now in 
TestDistributedShell.

It actually did the check. After SystemMetricsPublisher sends all the events, 
we do the getEntity call from ATS and check whether we have those events as 
well as specified data.

> RM needs to send update event with YarnApplicationState as Running to ATS/AHS

> Right now, Application in AHS/ATS is alway in ACCEPTED state until the 
> application finishes/Fails/is killed. This is because RM did not send any 
> other YarnApplicationState information, except FINISHED/FAILED/KILLED, to 
> ATS.
