Wangda Tan created YARN-3565:
--------------------------------

             Summary: 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
            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.
