> Reporter: Dong Lin
> Assignee: Dong Lin
>
> Currently PreferredLeaderElection will query zookeeper once for every
> partition that are included in the preferred leader election. This is very
> inefficient and makes the preferred leader election script slow. It should
> only query zookeeper once per topic.
> In addition, the script currently reports that the preferred leader election
> is successfully even if some partitions are not found in the zookeeper.
