norbert是一个方便做CS模式的集群的JAVA
API，norbert封装了zookeeper和netty，使用了协议栈缓存，基于SCALA开发

示例代码：

public class NorbertClient {
  public static void main(String[] args) {
    ClusterClient cc = new ZooKeeperClusterClient("norbert", "localhost:2181", 30000); (1)
    cc.awaiteConnectionUninterruptibly(); (2)
    cc.getNodes(); (3)
    cc.addListener(new MyClusterListener()); (4)
    cc.markNodeAvailable(1); (5).
    cluster.shutdown(6)
  }
}
