Mikhail Antonov commented on HBASE-11467:
-----------------------------------------
bq. How would we migrate a zk-based cluster to a master-based one?
You mean, to the cluster which has multiple masters and doesn't have ZK
connectivity on the client side, or to the cluster which doesn't have ZK
completely? For the former case, migration would require updating client jars
to pull in new code + modify config files to use masters connection instead of
connecting to ZK.
> New impl of Registry interface not using ZK + new RPCs on master protocol
