-----------------------------------
Thanks for working on this [~hrsharma]
I just kicked jenkins again, for some reason it didnt pick your patch... it
looks fine now
Just took a pass at your patch. I was wondering if in the Scheduler, instead of
deciding explicitly based on configuration whether to kill or pause, it should
just call a preempt method. Then if the ContainerExecutor + Runtime supports
pausing, it will pause the container and send a CONTAINER_PAUSED event to the
scheduler, else if it does not support pause/freezing, it will kill the
container and send CONTAINER_KILLED once it is killed.
> Expose configurable preemption policy for OPPORTUNISTIC containers running on
> the NM

> 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.
