Haibo Chen resolved MAPREDUCE-6929.
    Resolution: Not A Problem

> TimelineV2Client hangs MR AM
> ----------------------------
>                 Key: MAPREDUCE-6929
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6929
>             Project: Hadoop Map/Reduce
>          Issue Type: Improvement
>          Components: mr-am
>            Reporter: Haibo Chen
> 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.
