Fix Version/s: None
Currently to work around issue with secure cluster and how zkclient handles it we have https://issues.apache.org/jira/browse/TWILL-139
Since that time zkcient was fixed (fix in version 0.7)
But Twill still uses old version of kafka 0.8 that relies on 0.3 version of zkclient.
zkclient version 0.7 is included as a dependency since kafka 0.9.0.0.
That version of kafka introduces changes to APIs though.
This JIRA is to upgrade to later version of Kafka.
