Subject [jira] [Created] (YARN-3620) MetricsSystemImpl fails to show backtrace when an error occurs
Date Mon, 11 May 2015 20:28:59 GMT
Jason Lowe created YARN-3620:
--------------------------------

             Summary: MetricsSystemImpl fails to show backtrace when an error occurs
                 Key: YARN-3620
                 URL: https://issues.apache.org/jira/browse/YARN-3620
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Jason Lowe
            Assignee: Jason Lowe


While investigating YARN-3619 it was frustrating that MetricsSystemImpl was logging a ConcurrentModificationException
but without any backtrace.  Logging a backtrace would be very beneficial to tracking down
the cause of the problem.
