Guanghao Zhang commented on HBASE-16447:

Thanks. I try to generate a patch for branch-1. But I found that HBASE-11393 
was not merged to branch-1. The table-cfs config and namespace:table use the 
same colon separator. So we can't add table like "ns1:table1" to the peer 
config and only add table in default namespace. I thought we should fix this 
first in all branches which support namespaces.

> 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.
