> YARN-2877 introduced OPPORTUNISTIC containers, and YARN-5216 proposes to add capability to customize how OPPORTUNISTIC containers get preempted.
> In this JIRA we propose introducing a PAUSED container state.
> When a running container gets preempted, it enters the PAUSED state, where it remains until resources get freed up on the node then the preempted container can resume to the running state.
>  
> One scenario where this capability is useful is work preservation. How preemption is done, and whether the container supports it, is implementation specific.
> For instance, if the container is a virtual machine, then preempt would pause the VM and resume would restore it back to the running state.
> If the container doesn't support preemption, then preempt would default to killing the container.
