org.apache.hadoop.hbase.zookeeper.DrainingServerTracker
Tracks the list of draining region servers via ZK.
This class is responsible for watching for changes to the draining servers list. It handles adds/deletes in the draining RS list and watches each node.
If an RS gets deleted from draining list, we call {@link ServerManager#removeServerFromDrainList(ServerName)}
If an RS gets added to the draining list, we add a watcher to it and call {@link ServerManager#addServerToDrainList(ServerName)}


    this.regionServerTracker = new RegionServerTracker(zooKeeper, this,
        this.serverManager);
    this.regionServerTracker.start();


    this.drainingServerTracker = new DrainingServerTracker(zooKeeper, this,
      this.serverManager);
    this.drainingServerTracker.start();


    // Set the cluster as up.  If new RSs, they'll be waiting on this before
    // going ahead with their startup.
