Guanghao Zhang commented on HBASE-16653:
----------------------------------------

So the old RS still can read the old table-cfs znode and the old peer's 
replication still work on old rs. The only problem is we can't create new peer 
during rolling upgrade. I thought we need describe this in release note and 
hbase book.

> 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.
