---------------------------------------

Is this still an issue? With the goal to remove ZK, what is the impact on this ticket?

> We can make some improvements to the PreferredReplicaLeaderElection tool:
> 1. Terminate the tool if a controller is not up and running. Currently we can run the tool without having any broker running, which is kind of confusing. 
> 2. Should we delete /admin zookeeper path in PreferredReplicaLeaderElection (and ReassignPartition) tool at the end? Otherwise the next run of the tool complains that a replica election is already in progress. 
> 3. If there is an error, we can see it in cotroller.log. Should the tool also throw an error?
