--------------------------------------

             Summary: Reject to add a peer which replicate to itself earlier
                 Key: HBASE-24743
                 URL: https://issues.apache.org/jira/browse/HBASE-24743
             Project: HBase
          Issue Type: Improvement
            Reporter: Guanghao Zhang


Now there are one check in ReplicationSource#initialize method
{code:java}
// In rare case, zookeeper setting may be messed up. That leads to the incorrect
// peerClusterId value, which is the same as the source clusterId
if (clusterId.equals(peerClusterId) && 
!replicationEndpoint.canReplicateToSameCluster()) {
  this.terminate("ClusterId " + clusterId + " is replicating to itself: 
peerClusterId "
      + peerClusterId + " which is not allowed by ReplicationEndpoint:"
      + replicationEndpoint.getClass().getName(), null, false);
  this.manager.removeSource(this);
  return;
}
{code}
This check should move to AddPeerProcedure's precheck.
