Dear Folks,

Currently we don’t allow user to remove a dead server from a RSGroup.

https://github.com/apache/hbase/blob/e386ec566f89162e4aa08229f40a708ea3c9a038/hbase-server/src/main/java/org/apache/hadoop/hbase/rsgroup/RSGroupInfoManagerImpl.java#L899


There can be a scenario where a server is crashed due to hardware failure
and will not come back, admin would be interested in removing that server
from rsgroup which is not allowed.


IMO, it should be given a choice to user instead of restricting it.


Regards,

Pankaj
