[jira] [Commented] (OOZIE-1770) Create Oozie Application Master for YARN

["Robert Kanter (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OOZIE-1770?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14353690#comment-14353690 ] 

Robert Kanter commented on OOZIE-1770:
--------------------------------------

{quote}Interestingly, running a Container that doesn’t do much (e.g. a “Hello World” Java action), runs so fast, that Oozie is now the bottleneck. The callback comes in before the action has a chance to transition to RUNNING, so Oozie complains. We fixed this by adding a delay. We’ll probably want to improve this.{quote}
I believe this should be fixed by OOZIE-2126.  It fixes this requeueing the callback and retrying to "receive" it a few times to allow Oozie time to transition the action.

> After the first release of oozie on hadoop 2, it will be good if users can set execution engine in oozie conf, be it YARN AM or traditional MR. We can target this for post oozie 4.1 release.
