Jean-Daniel Cryans commented on HBASE-8640:
-------------------------------------------
Reverting this patch would indeed fix HBASE-9326, what you bind on should be
different from your identity.
The reason the region server does it differently, per my comment in HBASE-8148:
bq. For the master, the ServerName cannot be set like we do for the RS when it
reports for duty so I keep both the hostname that's normally set and the bind
address if configured so that the Master doesn't report as being "0.0.0.0".
> ServerName in master may not initialize with the configured ipc address of
> hbase.master.ipc.address

> We are starting rpc server with default interface hostname or configured ipc

> But we are initialzing servername with default hostname always master znode
