Date Thu, 01 Sep 2016 11:17:20 GMT

     [ https://issues.apache.org/jira/browse/HBASE-16447?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Guanghao Zhang updated HBASE-16447:
-----------------------------------
    Release Note: 
Support replication by namespaces config in peer.
1. Set a namespace in peer config means that all tables in this namespace will be replicated.
2. If the namespaces config is null, then the table-cfs config decide which table's edit can
be replicated. If the table-cfs config is null, then the namespaces config decide which table's
edit can be replicated.
3. If you already have set a namespace in the peer config, then you can't set any table of
this namespace to the peer config. If you already have set a table in the peer config, then
you can't set this table's namespace to the peer config.

  was:
Support replication by namespaces config.
1. Config a namespace in peer means that all tables in this namespace will be replicated.
2. If the peer didn't config any namespaces, then table-cfs config only decide which table's
edit can be replicated.
3. If the peer config a namespace, then the peer can't config any table of this namespace.
If the peer config a table, then the peer can't config this table's namespace too.

> Now we only config table cfs in peer. But in our production cluster, there are a dozen
of namespace and every namespace has dozens of tables. It was complicated to config all table
cfs in peer. For some namespace, it need replication all tables to other slave cluster. It
will be easy to config if we support replication by namespace. Suggestions and discussions
are welcomed.
