> 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.
