Mikhail Antonov commented on HBASE-11467:
-----------------------------------------

Also I would put it up on the review board, if you guys think that it'd be better reviewed
in one big patch, otherwise I can probably break it into some smaller ones.

> Currently there' only one implementation of Registry interface, which is using ZK to
get info about meta. Need to create implementation which will be using  RPC calls to master
the client is connected to.
> That includes adding several new methods to master RPC protocol:
> - GetMetaRegionLocation
> - IsTableOnlineState
> - GetCurrentNrHRS
> Additionally, new HTTP endpoint would be added to the master, so anyone can request ClusterId
without any authentication.
