Class ReplicationPeerManager

java.lang.Object

org.apache.hadoop.hbase.master.replication.ReplicationPeerManager

All Implemented Interfaces:

ConfigurationObserver

@InterfaceAudience.Private
public class ReplicationPeerManager
extends Object
implements ConfigurationObserver

Manages and performs all replication admin operations.

Used to add/remove a replication peer.

Implement ConfigurationObserver mainly for recreating ReplicationPeerStorage, for supporting migrating across different replication peer storages without restarting master.
