[jira] [Moved] (HADOOP-11958) MetricsSystemImpl fails to show backtrace when an error occurs

     [ https://issues.apache.org/jira/browse/HADOOP-11958?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jason Lowe moved YARN-3620 to HADOOP-11958:
-------------------------------------------

    Target Version/s: 2.7.1  (was: 2.7.1)
                 Key: HADOOP-11958  (was: YARN-3620)
             Project: Hadoop Common  (was: Hadoop YARN)

> 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.
