> In RpcClient, we cache the connection to each region server. When the
> connection goes bad, it stays in the cache till it's removed. Before it's
> removed, new calls will try to use it and just fail. The connection is a
> thread. It could be stuck in trying to receive some response. Before this
> receiving thread times out, it won't remove itself from the cache.
> It will be better to interrupt the receiving thread and let it clean up
> sooner.
