> Currently HConnectionImplementation works with the included RpcClient which
> is a direct implementation and not defined by an interface.
> It would be great to be able to swap out the default RpcClient with another
> implementation which can also be controlled by the default
> HConnectionImplementation.
> Suggested changes:
> - Create a RpcClient interface which defines all the ways
> HConnectionImplementation interacts with an RPC client. Like getting a
> blocking protobuf service interface or closing the client.
> - Define which RpcClient implementation to construct by setting a
> configuration variable which defaults to the current RpcClient.
> - Possibly create an abstract RpcClient class to only load all the basic Rpc
> layer configurations to be used in an implementation.
> Why? It enables experimentation with RpcClients which could enable new
> features or could be more performant than the included client.
> I created a new RpcClient implementation based on Netty which can also be
> called asynchronously. It would be great to also be able to use this
> RpcClient in all the default ways and tests to see if there are any issues
> with it.
