             Summary: Give up replicating anything in S state
                 Key: HBASE-20426
                 URL: https://issues.apache.org/jira/browse/HBASE-20426
             Project: HBase
          Issue Type: Sub-task
            Reporter: Duo Zhang

When we transit the remote S cluster to DA, and then transit the old A cluster 
to S, it is possible that we still have some entries which have not been 
replicated yet for the old A cluster, and then the async replication will be 

And this may also lead to data inconsistency after we transit it to DA back 
later as these entries will be replicated again, but the new data which are 
replicated from the remote cluster will not be replicated back, which introduce 
a whole in the replication.
