org.apache.curator.framework.recipes.leader.LeaderLatchListener
A LeaderLatchListener can be used to be notified asynchronously about when the state of the LeaderLatch has changed. Note that just because you are in the middle of one of these method calls, it does not necessarily mean that hasLeadership() is the corresponding true/false value. It is possible for the state to change behind the scenes before these methods get called. The contract is that if that happens, you should see another call to the other method pretty quickly.

    final LeaderLatch newLeaderLatch = new LeaderLatch(
        curator, ZKPaths.makePath(zkPaths.getCoordinatorPath(), COORDINATOR_OWNER_NODE), self.getHost()
    );


    newLeaderLatch.addListener(
        new LeaderLatchListener()
        {
          @Override
          public void isLeader()
          {
            DruidCoordinator.this.becomeLeader();
