Review comment:
ReplicationPeerManager is colocated with master, right? you can use
master.getClusterId() without doing all this? (that is cached, so saves a ZK
round trip).

Review comment:
You are fetching the currentClusterId right? Why name it as
peerClusterId? I think the argument to this method is peerClusterKey.

Review comment:
Replication#canReplicateToSameCluster() isn't it supposed to do this?
