> 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.
