[jira] [Created] (YARN-4774) ATS can block in shutdown under heavy load

Steve Loughran created YARN-4774:
------------------------------------

             Summary: ATS can block in shutdown under heavy load
                 Key: YARN-4774
                 URL: https://issues.apache.org/jira/browse/YARN-4774
             Project: Hadoop YARN
          Issue Type: Bug
          Components: timelineserver, webapp
    Affects Versions: 2.8.0
            Reporter: Steve Loughran
            Priority: Minor


seen in scale test teardown, ATS blocked in shutdown for some time; stack trace implies that jetty was waiting for threads to finish.

Hypothesis: the scale of the data being retrieved in a GET was large enough that the jetty worker threads weren't completing the operations, so blocking the {{stop()}} operation until they finally finished.

There is support in Jetty for a max shutdown time; this just isn't configured in YARN. It could be configured, and then ATS & other services could customise it.
