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

             Summary: Make the NodeManager's health checker service pluggable
                 Key: YARN-4271
                 URL: https://issues.apache.org/jira/browse/YARN-4271
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: nodemanager, resourcemanager
            Reporter: Subru Krishnan
            Assignee: Kishore Chaliparambil
             Fix For: 2.8.0


We introduce the notion of an RMProxy, running on each node (or once per rack). Upon start the AM is forced (via tokens and configuration) to direct all its requests to a new services running on the NM that provide a proxy to the central RM. 

This give us a place to:
1) perform distributed scheduling decisions
2) throttling mis-behaving AMs
3) mask the access to a federation of RMs
