Steve Loughran created YARN-1394:
------------------------------------
Summary: RM to inform AMs when a container completed due to NM
going offline -planned or unplanned
Key: YARN-1394
URL: https://issues.apache.org/jira/browse/YARN-1394
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Steve Loughran
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
