Heng Chen commented on HBASE-16653:
-----------------------------------

NO.  Not do it.  And old rs can't parse NS information due to it not support 
it.  So if you create one peer with NS during rolling upgrade,  the old RS 
replication will miss the ns information.

> Backport HBASE-11393 to all branches which support namespace

> As HBASE-11386 mentioned, the parse code about replication table-cfs config 
> will be wrong when table name contains namespace and we can only config the 
> default namespace's tables in the peer. It is a bug for all branches which 
> support namespace. HBASE-11393 resolved this by use a pb object but it was 
> only merged to master branch. Other branches still have this problem. I 
> thought we should fix this bug in all branches which support namespace.
