[jira] [Created] (MAPREDUCE-6929) TimelineClient hangs MR AM

Haibo Chen created MAPREDUCE-6929:
-------------------------------------

             Summary: TimelineClient 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.
