Konstantinos Karanasos commented on YARN-2884:
----------------------------------------------
Karthik, just a clarification: what is the current RMProxy responsible for?
As Carlo says, the functionality needed for the distributed scheduling is
explained in more detail in YARN-2885, where we introduce the LocalRM.
> Proxying all AM-RM communications

> Key: YARN-2884
> URL: https://issues.apache.org/jira/browse/YARN-2884
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager, resourcemanager
> Reporter: Carlo Curino
>
> 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
