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.
