1、zookeeper配置完毕之候报错，信息如下：
这是连接zookeeper的server一直不断的报错
2、查看zookeeper配置信息
2、在每个服务器上更改myid文件，如10.10.10.70文件
之候启动zookeeper，服务正常
- grid@master1:~$ zkCli.sh -server 10.10.10.70:2181
- ..............................

2、查看zookeeper配置信息

- dataLogDir=/data/zk/logs
- # the port at which the clients will connect

- # the maximum number of client connections.
