Examples of FServerTracker

com.alibaba.wasp.zookeeper.FServerTracker
Tracks the online fservers via ZK.
Handling of new RSs checking in is done via RPC. This class is only responsible for watching for expired nodes. It handles listening for changes in the RS node list and watching each node.
If an FS node gets deleted, this automatically handles calling of {@link com.alibaba.wasp.master.FServerManager#expireServer(com.alibaba.wasp.ServerName)}

    this.loadBalancerTracker.start();
    this.assignmentManager = new AssignmentManager(this, serverManager,
        this.balancer, this.executorService, this.metricsMaster);
    zooKeeper.registerListenerFirst(assignmentManager);


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


    this.drainingServerTracker = new DrainingServerTracker(zooKeeper, this,
