> Rsgroup name once is decided at the beginning, it is difficult to rename it.
> Current approach is removing all tables and servers back to default rsgroup, then delete it and add a rsgroup with the new name, after that moving regions and servers back. Or without moving back, if machine resources is ample. Anyway, it is an expensive operation:  moving regions, breaking region's locality.
> And given that rsgroup is one kind of managements in cluster, and management sometimes changes, renaming is necessary.
> It is simple in implementation. I'm working on it.
