    后来在官网查询之后发现官网写了这句话，意思大概是Curator 2.x.x-兼容两个zk 3.4.x 和zk 3.5.x，Curator 3.x.x-兼容兼容zk 3.5。

The are currently two released versions of Curator, 2.x.x and 3.x.x:Curator 2.x.x - compatible with both ZooKeeper 3.4.x and ZooKeeper 3.5.xCurator 3.x.x - compatible only with ZooKeeper 3.5.x and includes support for new features such as dynamic reconfiguration, etc.

       改完之后就可以。

       想起了之前玩kafka的时候也是遇到不兼容的问题，结论玩中间件要记得版本问题。
