Arun Suresh updated YARN-5292:
------------------------------
Description: This JIRA addresses the NM Container and state machine and
lifecycle changes needed to support pausing. (was: 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.
