stack commented on HBASE-4508:
------------------------------
I just tried this patch against the tip of 0.90. On a cluster loaded with
regions, I brought down one server, put in place a jar with this patch in place
and then brought it back up moving regions back on to the server. A client
that was not patched was able to talk to this server. It looks to me like this
patch is safe to backport.
