com.alibaba.wasp.zookeeper.DrainingServerTracker

Tracks the list of draining fservers via ZK.

This class is responsible for watching for changes to the draining servers list. It handles adds/deletes in the draining FS list and watches each node.

If an fs gets deleted from draining list, we call {@link com.alibaba.wasp.master.FServerManager#removeServerFromDrainList(com.alibaba.wasp.ServerName)}

If an fs gets added to the draining list, we add a watcher to it and call {@link com.alibaba.wasp.master.FServerManager#addServerToDrainList(com.alibaba.wasp.ServerName)}


    this.fserverTracker = new FServerTracker(zooKeeper, this,
        this.serverManager);
    this.fserverTracker.start();


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


    this.tableLockManager = new TableLockManager();
