-------------------------------------

Hi [~sunilg] this does not include support for FairScheduler. Are we planning to add that here or have a separate jira to track that work? Thx

> Currently during preemption, AM is notified with a list of containers which are marked for preemption. Introducing a timeout duration also along with this container list so that AM can know how much time it will get to do a graceful shutdown to its containers (assuming one of preemption policy is loaded in AM).
> This will help in decommissioning NM scenarios, where NM will be decommissioned after a timeout (also killing containers on it). This timeout will be helpful to indicate AM that those containers can be killed by RM forcefully after the timeout.
