Subject [jira] [Updated] (YARN-4019) Add JvmPauseMonitor to ResourceManager and NodeManager
Date Wed, 05 Aug 2015 01:04:04 GMT

     [ https://issues.apache.org/jira/browse/YARN-4019?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Robert Kanter updated YARN-4019:
    Attachment: YARN-4019.002.patch

The 002 patch fixes the NM checkstyle warning and the trailing whitespace.  The RM checkstyle
warning is due to a method that is "too long", but it's the {{serviceInit}} method, which
is setting things up, so I think we can ignore that.

I verified in a cluster that the metrics and log messages that come from the {{JvmPauseMonitor}}
show up.
