Subject [jira] [Commented] (YARN-4770) Auto-restart of containers should work across NM restarts.
Date Fri, 18 Nov 2016 00:52:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-4770?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15675321#comment-15675321

Jian He commented on YARN-4770:
-------------------------------

bq. If container crashed during the NM reboot, container would transit to RELAUNCHING state.
I will check it again.
Is this working now ? if so, we can close this.

on YARN-3998. Need to take care of two things:
>  - The relaunch feature needs to work across NM restarts, so we should save the retry-context
and policy per container into the state-store and reload it for continue relaunching after
NM restart.
>  - We should also handle restarting of any containers that may have crashed during the
NM reboot.
