> Key: YARN-1394

> YARN-914 proposes graceful decommission of an NM, and NMs already have the right to go offline.
> If AMs could be told that a container completed from an NM option -offline vs decommission, the AM could use that in its future blacklisting and placement policy.
> This matters in long-lived services which may like to place new instances where they were placed before, and track hosts failure rates
