Jun Rao commented on KAFKA-795:
-------------------------------

Is this a blocker for 0.8? If not, we should fix it in trunk.

> 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?
