Zheng Hu commented on HBASE-19782:
----------------------------------
If a table or namespace is in a synchronous peer between cluster A ( as
active) and cluster B ( as standby ), then we should reject any replication
entry (from both sync replication and async replication ) whose table or
namespace match the peer into cluster A (or cluster B) when it's DA or A
state.
> Reject the replication request when peer is DA state

>
> According to the design doc, we'll initialize both of the cluster state to
> DA after added the bidirectional replication path. and when a cluster in
> DA state, it'll reject replication request.
> so for cluster A and B in state DA, if any received replication entry whose
> table or namespace match the peer, the cluster will skip to apply into
> its local rs.
