Subject [jira] [Resolved] (YARN-4) Make ContainersMonitor pluggable
Date Fri, 08 May 2015 17:32:03 GMT

     [ https://issues.apache.org/jira/browse/YARN-4?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Vinod Kumar Vavilapalli resolved YARN-4.
    Resolution: Won't Fix

Went through the patch. It seems like this was originally created for CPU-isolation. But with
YARN-3, we have taken a completely different approach (creating cgroups instead of active
monitoring). ContainersMonitor is largely just used for memory-monitoring, so there is little
value in making it an abstraction.

Closing this as Won't Fix for now. [~adferguson], please reopen this if you disagree.
