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 add a new peer with no namespace/tablecfs config, the replicate_all flag
will be true
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.

> 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.
