[jira] [Commented] (YARN-3924) Submitting an application to standby
ResourceManager should respond better than Connection Refused
[ https://issues.apache.org/jira/browse/YARN-3924?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14626840#comment-14626840 ]
Xuan Gong commented on YARN-3924:
---------------------------------
The submit application request should re-direct to the active RM, does not it?

> Key: YARN-3924
> URL: https://issues.apache.org/jira/browse/YARN-3924
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Reporter: Dustin Cote
> Priority: Minor
>
> When submitting an application directly to a standby resource manager, the resource manager responds with 'Connection Refused' rather than indicating that it is a standby resource manager. Because the resource manager is aware of its own state, I feel like we can have the 8032 port open for standby resource managers and reject the request with something like 'Cannot process application submission from this standby resource manager'.
> This would be especially helpful for debugging oozie problems when users put in the wrong address for the 'jobtracker' (i.e. they don't put the logical RM address but rather point to a specific resource manager).
