https://github.com/apache/storm/pull/2378
According to https://curator.apache.org/zk-compatibility.html, Curator
4.0.x supports both ZK versions, but we still need to keep an eye of ZK
version. If we want to support Zookeeper 3.4.x, we need to **exclude**
Zookeeper dependency from `curator-recipes` and add Zookeeper dependency
manually.
Does the patch work with Zookeeper 3.4.x? We still need to consider
supporting Zookeeper 3.4.x first, cause Zookeeper 3.5.x is still announced as
'beta' and most of our end users don't want to explore the beta in production.
