Description

AkkaRpcEnv is very noisy about errors. Every time some actor disconnects, you see a big nasty error in the output. If you're running with dynamic allocation on, that can affect the usability of the spark-shell, for example.

And, to be frank, those "errors" are not interesting. If they're real errors, the endpoints responsible for monitoring them will take action and log real, useful error messages.
