Jørgen commented on KAFKA-14922:
--------------------------------
An _improvement_ would be to only return topics that exactly contains the
applicationId provided.
This would fix the case where an applicationId doesn't exist instead of
returning all topics that starts with provided applicationId (like "f" in the
example).
Would not cover the case where other applicationIds starts with applicationId
provided (foo-v1 would delete foo-v1-2 topics, etc)
> kafka-streams-application-reset deletes topics not belonging to specified
> application-id

> Project: Kafka
> Issue Type: Bug
> Components: streams, tools
> Affects Versions: 3.4.0
> Reporter: Jørgen
> Priority: Major

> When running the command _kafka-streams-application-reset --bootstrap-servers
> $BOOTSTRAP --application-id foo_ all internal topics that _starts with_ foo
> is deleted. This happens even if there's no application-id named foo.
> Example:
> {code:java}
> Application IDs:
> foo-v1
> foo-v2
> Internal topics:
> foo-v1-repartition-topic-repartition
> foo-v2-repartition-topic-repartition
> Application reset:
> kafka-streams-application-reset --bootstrap-servers $BOOTSTRAP
> --application-id foo
> > No input or intermediate topics specified. Skipping seek.
> Deleting inferred internal topics [foo-v2-repartition-topic-repartition,
> foo-v1-repartition-topic-repartition]
> Done.{code}
> Expected behaviour is that the command fails as there are no application-id's
> with the name foo instead of deleting all foo* topics.
> This is critical on typos or if application-ids starts with the same name as
> others (for example if we had foo-v21 and wanted to reset foo-v2)
> The bug should be located here:
> [https://github.com/apache/kafka/blob/c14f56b48461f01743146d58987bc8661ba0d459/tools/src/main/java/org/apache/kafka/tools/StreamsResetter.java#L693]
> Should check that the topics matches the application-id exactly instead of
> checking that it starts with the application-id.
