Xiaolin Ha commented on HBASE-19326:
------------------------------------
[~andrewcheng][~stack]
In docs it said that 'The default group is not like other rsgroups in that it
is dynamic. Its server list mirrors the current
state of the cluster; i.e. if you shutdown a server that was part of the
default rsgroup, and then do a
get_rsgroup default to list its content in the shell, the server will no longer
be listed. For non-default
groups, though a mode may be offline, it will persist in the non-default
group’s list of servers. But if
you move the offline server from the non-default rsgroup to default, it will
not show in the default
list. It will just be dropped.'
But when a regionserver is dead and master is restarted, the regionserver can
be removed from the non-default rsgroup too.
Is this conflict with the doc? Do you think dead regionservers can be removed
either?

> deadserver list in ServerManager.
> But rsgroup still contains these dead servers, so we should also remove dead
> servers from the group information.
