-----------------------------------------
Hi [~wangda], I would like to work on this jira and i was also similarly
thinking in distributed case how to support exclusivity/constraints !
> NodeHeartbeatRequest/RegisterNodeManagerRequest should use NodeLabel object
> instead of String
> ---------------------------------------------------------------------------------------------

> Key: YARN-3565
> URL: https://issues.apache.org/jira/browse/YARN-3565
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: api, client, resourcemanager
> Reporter: Wangda Tan
> Assignee: Wangda Tan
> Priority: Blocker
>
> Now NM HB/Register uses Set<String>, it will be hard to add new fields if we
> want to support specifying NodeLabel type such as exclusivity/constraints,
> etc. We need to make sure rolling upgrade works.
