今天在做dubbo实验的时候，碰到一个问题，卡了我7-8小时，差了很多资料无果，错误如下

最后发现是尝试，在我自己程序运行端（也就是java程序跑的所在机器，我自己的笔记本电脑上，加入了zk服务器的ip和服务器名映射关系，没想到竟然解决了，我只能说操蛋啊，查了几个小时，因为是spring或者是程序配置问题，主要引起我注意的是Will not attempt to authenticate using SASL (unknown error)那句。。。）

1.这里1.1.1.2是zk的服务器端IP地址，我在服务器上也配置了1.1.1.2和服务器本机的IP地址映射关系，不然也可以出问题

2.在  C:\\Windows\\System32\\drivers\\etc\\hosts 里加入 1.1.1.2  ubuntu16这句话，问题就解决了。。。

3.补充一下，发现zk服务器端不配置映射关系似乎也可以用，但是zk客户端，是一定要配置的
