Ashish Singhi commented on HBASE-16868:
---------------------------------------
+1 on the patch.
Nit(can address on the commit):
{code}
31 If replicate_all flag is false, then all user tables cannot be
replicate to
32 peer cluster. But you can set NAMESPACES or TABLECFS to include some
tables
33 which will be replicated.
{code}
It will be good if we can explain the user here, how to set NAMESPACES or
TABLECFS. We can just mention the command which one to use to do it.
> 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.
