Subject [jira] [Commented] (YARN-1577) Unmanaged AM is broken because of YARN-1493
Date Sat, 22 Mar 2014 00:52:48 GMT

    [ https://issues.apache.org/jira/browse/YARN-1577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13943800#comment-13943800

Vinod Kumar Vavilapalli commented on YARN-1577:
-----------------------------------------------

Quickly scanned the patch. It looks like an existing bug, but it looks like even if the app
fails immediately for some reason, client will still be stuck for 10min wait timeout.

> Today unmanaged AM client is waiting for app state to be Accepted to launch the AM. This
is broken since we changed in YARN-1493 to start the attempt after the application is Accepted.
We may need to introduce an attempt state report that client can rely on to query the attempt
state and choose to launch the unmanaged AM.
