Most likely it is needed just to update zookeper library:
* Current version: _<zookeeper.version>*3.5.7*</zookeeper.version>_
* Latest version: _*3.6.2*_
_[https://mvnrepository.com/artifact/org.apache.zookeeper/zookeeper
]_
So current issue is minor, but updating Zookeper library can be major and easy
or not easy (it depends). The separate task for updating Zookeper library can
be created
