Haibo Chen commented on MAPREDUCE-6929:
---------------------------------------
You are right, [~jlowe]. Trying to reproduce this, I found that the AM did
finally exit, with a 3-minutes delay after MRAppMaster calls this.stop(),
during which the TimelineV2Client was trying to write and failing. I was being
too impatient to wait for it to finish.
> TimelineV2Client hangs MR AM

> I happened to misconfigure ATSv2 settings, that is, I enabled emitting to
> ATSv2 in MR and did not start YARN with ATSv2. The job was stuck after it
> finished all its work.
> Noticed that in MRAppMaster, TimelineClient is never added as a service,
> which I think is why the AM was hanging.
