Zheng Hu commented on HBASE-18822:
----------------------------------
bq. What will happen when a user doesn't explicitly specify any namespace or
table in replication peer config ?
Depends on the peer's replicateAllUserTables, if true, then will replicate to
peer, if false then won't. you can see the RepliationUtils#contains method
https://github.com/apache/hbase/blob/master/hbase-replication/src/main/java/org/apache/hadoop/hbase/replication/ReplicationUtils.java#L160
We use it to decide whether need to replicate ddl or not :-)
> Create table for peer cluster automatically when creating table in source
> cluster of using namespace replication.
