-------------------------------
Is this a blocker for 0.8? If not, we should fix it in trunk.
> Improvements to PreferredReplicaLeaderElection tool

> Key: KAFKA-795
> URL: https://issues.apache.org/jira/browse/KAFKA-795
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.8
> Reporter: Swapnil Ghike
> Assignee: Swapnil Ghike
> Priority: Blocker
> Labels: kafka-0.8, p2
> Fix For: 0.8

> 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?
