----------------------------------
Thanks [~giovanni.fumarola]. Took a brief look at the patch and discussed with
[~subru] offline. The general approach looks fine.

> As detailed in the proposal in the umbrella JIRA, we are introducing a new
> component that routes client request to appropriate ResourceManager(s). This
> JIRA tracks the creation of a proxy for ApplicationClientProtocol in the
> Router. This provides a placeholder for:
> 1) throttling mis-behaving clients (YARN-1546)
> 3) mask the access to multiple RMs (YARN-3659)
> We are planning to follow the interceptor pattern like we did in YARN-2884 to
> generalize the approach and have only dynamically coupling for Federation.
