Hua Liu commented on YARN-3224:
-------------------------------
This feature is very helpful. AM can choose to stop sending new tasks to the
to-be-preempted containers on decommissioning hosts. Will the author do a
rebase and try to commit it?
> Notify AM with containers (on decommissioning node) could be preempted after
> timeout.
