> The NotServingRegionException exception is thrown when the remote server is
> no longer serving the asked-for region (usually because its been split). The
> server throws the exception to provoke the client into making a new
> interrogation of region locations.
> It would be an improvement if such 'normal' operation was not built atop
> exceptions. For example, commits might return a 'region moved' message.
