Subject Re: Getting clear on which version of zookeeper to use … and what to deploy for a production environment.

Interesting.

I did this in a maven pom just now:

   <dependency>
      <groupId>org.apache.zookeeper</groupId>
      <artifactId>zookeeper</artifactId>
      <version>3.3.3</version>
    </dependency>

Everything seems to have resolved just fine.
