> Topic deleted during reassignment
> ---------------------------------
>
> Key: KAFKA-14245
> URL: https://issues.apache.org/jira/browse/KAFKA-14245
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 2.7.1
> Reporter: Junyang Liu
> Priority: Blocker
>
> 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.
