Junping Du commented on YARN-2561:
----------------------------------
Thanks [~jlowe] for the comments! Yes. Checking running containers reported by
NM seems to be a better way given each NM's recovery configuration is possible
to be different (although we don't encourage this configuration. Isn't it?). v3
patch use the new way.
> MR job client cannot reconnect to AM after NM restart.
