Date Wed, 08 Jun 2016 21:10:21 GMT

     [ https://issues.apache.org/jira/browse/YARN-5216?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arun Suresh updated YARN-5216:
------------------------------
    Description: 
Currently, the default action taken by the QueuingContainerManager, introduced in YARN-2883,
when a GUARANTEED Container is scheduled on an NM with OPPORTUNISTIC containers using up resources,
is to KILL the running OPPORTUNISTIC containers.

This JIRA proposes to expose a configurable hook to allow the NM to take a different action.
