Description

I tried to run `DiscoveryExample` to simulate service discovery, when I first entered list to see the list of registrations, I found that the process exited directly, I checked the code and found that the code threw `NoNodeException` but it was ignored.

I think if there is no service registered, using `list` should tell me that no service is registered instead of just ignoring the exception and closing the connection, so I am asking this question, what do you think?
