>             Project: HBase
>          Issue Type: New Feature
>          Components: Replication

> 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.
