> -------------------------------------------------------------------------------------------------

> Key: KAFKA-13394
> URL: https://issues.apache.org/jira/browse/KAFKA-13394
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 3.1.0
> Reporter: Justine Olshan
> Assignee: Justine Olshan
> Priority: Major
>
> With KAFKA-13102, we added topic IDs to the InitialFetchState and the
> PartitionFetchState in order to send fetch requests using topic IDs when ibp
> is 3.1.
> However, there are some cases where we could initially send topic IDs from
> the controller and then no longer to do so (controller changes to an IBP <
> 2.8). If we do not remove from the PartitionFetchState and one broker is
> still IBP 3.1, it will try to send a version 13 fetch request to brokers that
> no longer have topic IDs in the metadata cache. This could leave the cluster
> in a state unable to fetch from these partitions.
