Subject [jira] [Commented] (HADOOP-15081) org.apache.hadoop.util.JvmPauseMonitor Detected pause in JVM or host machine (eg GC) cause ResourceManager exit
Date Fri, 01 Dec 2017 14:01:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16274433#comment-16274433

Jason Lowe commented on HADOOP-15081:
-------------------------------------

The JvmPauseMonitor does not call System.exit (or proxies to it like ExitUtil), so I don't
see how JvmPauseMonitor could be responsible for the process exiting.  Do you have evidence
other than the log message appears towards the end of the logs?  What seems more likely is
that there is memory pressure to the point that out of memory errors are being thrown and
caught by the YarnUncaughtExceptionHandler.  Check the stderr log to see if there's a message
about halting the system due to out of memory errors.
