Guanghao Zhang updated HBASE-16868:
    Release Note: Add a replicate_all flag to replication peer config. The 
default value is true, which means all user tables (REPLICATION_SCOPE != 0 ) 
will be replicated to peer cluster. If you only need replicate some namespaces 
or tables,  you need set replicate_all flag to false first. Then add special 
namespaces or table-cfs config to the replication peer.

> Add a replicate_all flag to avoid misuse the namespaces and table-cfs config 
> of replication peer

> First add a new peer by shell cmd.
> {code}
> add_peer '1', CLUSTER_KEY => "server1.cie.com:2181:/hbase".
> {code}
> If we don't set namespaces and table cfs in peer config. It means replicate 
> all tables to the peer cluster.
> Then append a table to the peer config.
> {code}
> append_peer_tableCFs '1', {"table1" => []}
> {code}
> Then this peer will only replicate table1 to the peer cluster. It changes to 
> replicate only one table from replicate all tables in the cluster. It is very 
> easy to misuse in production cluster. So we should avoid appending table to a 
> peer which replicates all table.
