解决方案:Curator 版本调到2.9.0

原理:

根据curator 官网提示http://curator.apache.org/zk-compatibility.html

ZooKeeper 3.5.x

• Curator 4.0 has a hard dependency on ZooKeeper 3.5.x
• If you are using ZooKeeper 3.5.x there's nothing additional to do - just use Curator 4.0

ZooKeeper 3.4.x

Curator 4.0 supports ZooKeeper 3.4.x ensembles in a soft-compatibility mode. To use this mode you must exclude ZooKeeper when adding Curator to your dependency management tool.
