> Key: KAFKA-4074
> URL: https://issues.apache.org/jira/browse/KAFKA-4074
> Project: Kafka
> Issue Type: Bug
> Components: controller
> Reporter: Joel Koshy
> Assignee: Manikumar Reddy
> Fix For: 0.10.1.0
>
>
> The {{delete.topic.enable}} configuration does not completely block the
> effects of delete topic since the controller may (indirectly) query the list
> of topics under the delete-topic znode.
> To reproduce:
> * Delete topic X
> * Force a controller move (either by bouncing or removing the controller
> znode)
> * The new controller will send out UpdateMetadataRequests with leader=-2 for
> the partitions of X
> * Producers eventually stop producing to that topic
> The reason for this is that when ControllerChannelManager adds
> UpdateMetadataRequests for brokers, we directly use the partitionsToBeDeleted
> field of the DeleteTopicManager (which is set to the partitions of the topics
> under the delete-topic znode on controller startup).
> In order to get out of the situation you have to remove X from the znode and
> then force another controller move.
