[jira] [Created] (HBASE-16868) Avoid appending table to a peer
which replicates all tables
Guanghao Zhang created HBASE-16868:
--------------------------------------
Summary: Avoid appending table to a peer which replicates all tables
Key: HBASE-16868
URL: https://issues.apache.org/jira/browse/HBASE-16868
Project: HBase
Issue Type: New Feature
Components: Replication
Affects Versions: 2.0.0
Reporter: Guanghao Zhang
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.
