bq. What is the 'misuse' we are trying to avoid?
In our production cluster, there are hundreds of tables. And there are a peer
'1' to replicate all user tables to a peer cluster. If a newbee of hbase create
a new table 't1'. Then he want replicate it to peer cluster and run
append_peer_tableCFs '1', {"table1" => []} in hbase shell. Then we will meet
this problem: all other tables will cannot be replicated to peer cluster!

> 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.
