Description

There's nothing inherently wrong in the replication design that prevents master-master, but it was disabled in the code in order to reduce the scope of HBASE-2223. Specifically, this code from Replication just needs a simple 2 lines modification to always instantiate ReplicationSink if this.replication is true:

  public void startReplicationServices() throws IOException {
    if (this.replication) {
      if (this.replicationMaster) {
        this.replicationManager.init();
      } else {
        this.replicationSink =
            new ReplicationSink(this.conf, this.stopRequested);
      }
    }
  }

Enable and test.
