---------------------------------
Priority: Minor (was: Major)
> 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
> Priority: Minor
> 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
