> Do not retry rpc calls If the proxy contains unresolved address

>
> When the InetSocketAddress object happens to be unresolvable (e.g. due to
> transient DNS issue), the rpc proxy object will not be usable since the
> client will throw UnknownHostException when a Connection object is created.
> If FailoverOnNetworkExceptionRetry is used as in the standard HA failover
> proxy, the call will be retried, but this will never recover. Instead, the
> validity of address must be checked on pxoy creation and throw if it is
> invalid.
