----------------------------------------

Hi [~Naganarasimha]
Thnks for the comments.

I would suggest only to have only 1 resync configuration and remove what we introduced for
YARN-4106.

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 &
resync.
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.
