Review comment:
When there is no one service in the registration call list will directly
exit the process, and in fact should be prompted without any services, unless
it is other exceptions, do you think?

> 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?
