Karthik Kambatla commented on YARN-2884:
----------------------------------------

Given we already have an RMProxy, can we go with LocalRM as Sriram suggested on 
YARN-2877?

> 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
