[jira] [Created] (YARN-5798) Handle FSPreemptionThread crashing due to a RuntimeException

Karthik Kambatla created YARN-5798:
--------------------------------------

             Summary: Handle FSPreemptionThread crashing due to a RuntimeException
                 Key: YARN-5798
                 URL: https://issues.apache.org/jira/browse/YARN-5798
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: fairscheduler
    Affects Versions: 2.9.0
            Reporter: Karthik Kambatla


YARN-5605 added an FSPreemptionThread. The run() method catches InterruptedException. If this were to run into a RuntimeException, the preemption thread would crash. We should probably fail the RM itself (or transition to standby) when this happens.
