> A real problem in our production cluster. A user point that his table's data
> can't be replicate to the peer cluster. Then we start to debug the reason. We
> checked the replication scope, checked the replication wal entry filter, and
> check the namespace,tablecfs config. But didn't found any problem. We enabled
> the RS's debug log to find the reason. Finally, we found use use put with
> skip wal to write data. But it taked a long time... Our replication use wal
> to replicate data. So the data can't be replicated to peer cluster. I thought
> throw a exception may be better for user if the table's replication scope is
> not 0. (as 0 means not replicated).
