Zookeeper 异常 ConnectionLossException 怎么办？

一、appps/zookeeper3.4.5/conf/zoo.cfg配置

二、防火墙状态
2.1、Windows防火墙状态

2.2、Linux防火墙状态

三、Windows可ping通虚拟机IP

四、通过SecureCRT对打开zookeeper（三个虚拟机中zookeeper均正常）


五、Java代码
package cn.itcast.bigdata.zk;
import java.io.IOException;
import org.apache.zookeeper.CreateMode;
import org.apache.zookeeper.WatchedEvent;
import org.apache.zookeeper.Watcher;
import org.apache.zookeeper.ZooKeeper;
import org.apache.zookeeper.ZooDefs.Ids;

public class SimpleZKClient_1 {
    private static final String connectString = "192.168.64.102:2181,192.168.64.103:2181,192.168.64.104:2181";
    private static final int sessionTimeout = 2000;
    public static void main(String[] args) throws Exception {
        ZooKeeper zkClient = new ZooKeeper(connectString,sessionTimeout, new Watcher() {
            @Override
            public void process(WatchedEvent event) {
                // TODO Auto-generated method stub
                System.out.println(event.getType() + "---" + event.getPath());
            }
        });
            String nodeCreated = zkClient.create("/eclipse", "hellozk".getBytes(), Ids.OPEN_ACL_UNSAFE, CreateMode.PERSISTENT); 
    }
}

六、运行，报错

求大神帮助。。。。。
