Vishal Kathuria commented on HBASE-3833:
----------------------------------------
Sorry for the radio silence on this issue folks. I have updated the patch with
the comments. The biggest change is that now we wait for the region servers to
be reassigned before adding the node to expire server list (which will trigger
node shutdown).
Please let me know if you have any further comments.
Also, let me know if we need to have some sort of timeout and if the region
servers aren't migrated within that timeout, then we kill the region server
anyway. I got this suggestion from Karthik, but wanted to see what other folks
think before implementing it.

> An HBase cluster currently does not have the ability to specify that the
> master should accept regionservers only from a specified list. This helps
> preventing administrative errors where the same machine could be included in
> two clusters. It also allows the administrator to easily remove un-ssh-able
> machines from the cluster.
