stack commented on HBASE-11467:
-------------------------------

Why does client need to provide clusterid authenticating?  The cluster knows 
its clusterid.  The client is specifying the cluster it wants to connect too 
when it choses a zk ensemble.  I suppose the client could provide it as part of 
its connection string but seems like a pain to users having to specify cryptic 
string in local config for the client to volunteer on connection setup.

> New impl of Registry interface not using ZK + new RPCs on master protocol
