Subject [jira] [Commented] (YARN-4176) Resync NM nodelabels with RM every x interval for distributed nodelabels
Date Thu, 17 Sep 2015 09:14:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4176?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14791827#comment-14791827

Bibin A Chundatt commented on YARN-4176:

Hi [~Naganarasimha]
Thnks for the comments.

I would suggest only to have only 1 resync configuration and remove what we introduced for
Will be taken care 
So node labels will be sent to RM either if node labels are modified since the last heartbeat
or the resync-interval has elapsed right ?
Currently on hearbeat we are sending only when update happens.  Will be *or* of update &
Changing to {{System.nanoTime()}} will handle too.

> This JIRA is for handling the below set of issue
> # Distributed nodelabels after NM registered with RM if cluster nodelabels are removed
and added then NM doesnt resend labels in heartbeat again untils any change in labels
> # NM registration failed with Nodelabels should resend labels again to RM 
> The above cases can be handled by  resync nodeLabels with RM every x interval
> # Add property {{yarn.nodemanager.node-labels.provider.resync-interval-ms}} and  will
resend nodelabels to RM based on config no matter what the registration fails or success.
