Andrew Purtell commented on HBASE-19326:
----------------------------------------
This seems like a fine change to have. It allows the admin to remove servers
from the RSgroup but will disallow that if the servers were in the group, but
are now dead (or recovering) and may come back.
It also disallows removal of live servers. Is that intentional? So the command
will be useful only for removing decommissioned servers. Maybe instead of
'dead' you mean 'decommissioned'?

> In HBASE-18131, we add an hbase shell command {{clear_deadservers}} to clear
> deadserver list in ServerManager.
> But rsgroup still contains these dead servers, so we should also remove dead
> servers from the group information.
