> When Doing partition reassignment, the partition should not be deleted. But in the method "markTopicIneligibleForDeletion", topics need to be in "controllerContext.topicsToBeDeleted" while this is usually false because topics are not deleted at that time. This makes the topics doing reassignment not able to be added to "topicsIneligibleForDeletion". So when topic deletion comes, the topic in reassignment can also be deleted, which leads to the result that the reassignment can never be finished.
