[jira] [Commented] (YARN-2829) After restart, RM should create running-attempt before AM register

    [ https://issues.apache.org/jira/browse/YARN-2829?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14544317#comment-14544317 ] 

Jian He commented on YARN-2829:
-------------------------------

I think it's now already the case that attempts are added into scheduler synchronously.
closing this. please re-open if disagree.

> bq. I think there is more that we can and should do but in the near future. In the non-restart control flow, AMs cannot register till the RM knows about the attempt (obviously), this condition is invalidated after restart. Will file a ticket.
