org.apache.hadoop.hbase.replication.ReplicationZookeeper

This class serves as a helper for all things related to zookeeper in replication.

The layout looks something like this under zookeeper.znode.parent for the master cluster:

 replication/ state      {contains true or false} clusterId  {contains a byte} peers/ 1/   {contains a full cluster address} peer-state  {contains ENABLED or DISABLED} 2/ ... rs/ {lists all RS that replicate} startcode1/ {lists all peer clusters} 1/ {lists hlogs to process} 10.10.1.76%3A53488.123456789 {contains nothing or a position} 10.10.1.76%3A53488.123456790 ... 2/ ... startcode2/ ...

    // I can close myself when comes time.
    Configuration conf = new Configuration(config);
    super.setConf(conf);
    try {
      ZooKeeperWatcher zkw = new ZooKeeperWatcher(conf, "replicationLogCleaner", null);
      this.zkHelper = new ReplicationZookeeper(this, conf, zkw);
    } catch (KeeperException e) {
      LOG.error("Error while configuring " + this.getClass().getName(), e);
    } catch (IOException e) {
      LOG.error("Error while configuring " + this.getClass().getName(), e);
    }
