> Project: Hadoop Common
> Issue Type: Improvement
> Components: ipc
> Affects Versions: 0.24.0

> Assignee: Aaron T. Myers
> Fix For: 0.24.0

>
> The process to clean up an RPC proxy object is to call RPC.stopProxy, which
> looks up the RPCEngine previously associated with the interface which that
> proxy object provides and calls RPCEngine.stopProxy passing in the proxy
> object. Every concrete implementation of RPCEngine.stopProxy then looks up
> the invocation handler associated with the proxy object and calls close() on
> that invocation handler.
> This process can be simplified by cutting out the steps of looking up the
> previously-registered RPCEngine, and instead just having RPC.stopProxy
> directly look up the invocation handler for the proxy object and call close()
> on it.
