[jira] [Created] (YARN-4264) In-VM test ATS instances fail with metrics already registered

Steve Loughran created YARN-4264:
------------------------------------

             Summary: In-VM test ATS instances fail with metrics already registered
                 Key: YARN-4264
                 URL: https://issues.apache.org/jira/browse/YARN-4264
             Project: Hadoop YARN
          Issue Type: Bug
          Components: timelineserver
    Affects Versions: 2.8.0
            Reporter: Steve Loughran


Testing my SPARK-1537 code against branch-2 triggers stack traces due to failed attempts to re-register metrics. This is with code which works against 2.7.1, so it's a regression.

Either the timeline server needs to unregister its metrics on shutdown, or ATS adds an option to disable metrics for test purposes.
