Have you considered sticking a proxy in front of the cluster?
It may be quite effective (and HAproxy supports several load balancing
modes, including “least connected” and client IP hashing).

This would still require clients to reconnect after node recovery
but sounds a lot less intrusive than shutting down the entire system.
