Description

Two variables should be exchanged in KafkaController.scala as follows：
val topicsForWhichPartitionReassignmentIsInProgress = controllerContext.partitionsUndergoingPreferredReplicaElection.map(_.topic)
val topicsForWhichPreferredReplicaElectionIsInProgress = controllerContext.partitionsBeingReassigned.keySet.map(_.topic)
val topicsIneligibleForDeletion = topicsWithReplicasOnDeadBrokers | topicsForWhichPartitionReassignmentIsInProgress |
topicsForWhichPreferredReplicaElectionIsInProgress

Should change to:
val topicsForWhichPreferredReplicaElectionIsInProgress = controllerContext.partitionsUndergoingPreferredReplicaElection.map(_.topic)
val topicsForWhichPartitionReassignmentIsInProgress = controllerContext.partitionsBeingReassigned.keySet.map(_.topic)
val topicsIneligibleForDeletion = topicsWithReplicasOnDeadBrokers | topicsForWhichPartitionReassignmentIsInProgress |
topicsForWhichPreferredReplicaElectionIsInProgress
