 在此之前将冲突不兼容的curator从2.11.1改成了2.10，后来是2.10.0，不存在2.10这个版本。

Curator 存在版本兼容问题。

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。

Versions
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.x
Curator 3.x.x - compatible only with ZooKeeper 3.5.x and includes support for new features such as dynamic reconfiguration, etc.
