--------------------------
Issue Type: Sub-task (was: Task)
Parent: YARN-2492
> Support NodeLabelsProvider at Resource Manager side
> ---------------------------------------------------
>
> Key: YARN-3964
> URL: https://issues.apache.org/jira/browse/YARN-3964
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Dian Fu
>
> Currently, CLI/REST API is provided in Resource Manager to allow users to
> specify labels for nodes. For labels which may change over time, users will
> have to start a cron job to update the labels. This has the following
> limitations:
> - The cron job needs to be run in the YARN admin user.
> - This makes it a little complicate to maintain as users will have to make
> sure this service/daemon is alive.
> Adding a Node Labels Provider in Resource Manager will provide user more
> flexibility.
