Subject [jira] [Created] (YARN-7052) RM SchedulingMonitor should use HadoopExecutors when creating ScheduledExecutorService
Date Fri, 18 Aug 2017 21:53:00 GMT
Eric Payne created YARN-7052:
--------------------------------

             Summary: RM SchedulingMonitor should use HadoopExecutors when creating ScheduledExecutorService
                 Key: YARN-7052
                 URL: https://issues.apache.org/jira/browse/YARN-7052
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn
            Reporter: Eric Payne


In YARN-7051, we ran into a case where the preemption monitor thread hung with no indication
of why. This was because the preemption monitor is started by the {{SchedulingExecutorService}}
from {{SchedulingMonigor#serviceStart}}, and then nothing ever gets the result of the future
or allows it to throw an exception if needed.

At least with {{HadoopExecutor}}, it will provide a {{HadoopScheduledThreadPoolExecutor}}
that logs the exception if one happens.
