问题： zookeeper-345 的安装出现了奇怪问题
描述: 启动zookeeper后看到2181端口已经占用
然后运行：zkCli.sh -server server1:2181
运行后在welcome to zookeeper!后不断出错误信息：
2013-06-06 20:03:06,014 [myid:] - INFO [main-SendThread(localhost:2181):ClientCnxn$SendThread@966] - Opening socket connection to server localhost/0:0:0:0:0:0:0:1:2181. Will not attempt to authenticate using SASL (unknown error)
