title: Does leader election need to be executed in separate step after setting up 3-machine ensemble?
body: <p>I currently have 3 machines in a Zookeeper ensemble - I've already set up the configuration file, and the 3 machines in the ensemble can communicate with each other. </p>
  
  <p>What exactly is leader election? Do I need to use a LeaderLatch to start leader election, or does it happen automatically after correctly setting up the configuration file?</p>
