> After running kafka-preferred-replica-election.sh once, a second run will fail with "Preferred replica leader election currently in progress for ...".
> The /admin/preferred_replica_election key is never deleted from ZooKeeper, because the "isTriggeredByAutoRebalance" parameter to onPreferredReplicaElection (https://github.com/apache/kafka/blob/0ffec142a991849833d9767be07e895428ccaea1/core/src/main/scala/kafka/controller/KafkaController.scala#L614) is used incorrectly. In the automatic case (https://github.com/apache/kafka/blob/0ffec142a991849833d9767be07e895428ccaea1/core/src/main/scala/kafka/controller/KafkaController.scala#L1119), it is set to false. In the manual case (https://github.com/apache/kafka/blob/0ffec142a991849833d9767be07e895428ccaea1/core/src/main/scala/kafka/controller/KafkaController.scala#L1266) the parameter is not passed, so it defaults to true.
