Subject [jira] [Commented] (YARN-1394) RM to inform AMs when a container completed due to NM going offline -planned or unplanned

    [ https://issues.apache.org/jira/browse/YARN-1394?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15362610#comment-15362610

Junping Du commented on YARN-1394:
----------------------------------

This jira sounds like have overlap with YARN-3224. Given YARN-3224 already have patch there,
shall we mark this as duplicated? CC [~stevel@apache.org], [~rohithsharma] and [~sunilg].

> 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
