>
> The error message is not friendly when RPS cannot be connected.
> We expect a more clear message printed out, for example, "cannot connect to
> RPS service: host/port/service ".
> What's more, there are many other error and log messages and log level should
> be refined to more friendly. Some unused log should be removed.
