Matthias J. Sax reassigned KAFKA-20885:
---------------------------------------
Assignee: Matthias J. Sax
> Incorrect IQ metadata in "streams" protocol
> -------------------------------------------
>
> Key: KAFKA-20885
> URL: https://issues.apache.org/jira/browse/KAFKA-20885
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 4.1.0
> Reporter: Matthias J. Sax
> Assignee: Matthias J. Sax
> Priority: Major
>
> Note, I am setting 4.1.0 as affected version, because this code shipped with
> 4.1.0, even if "streams" protocol is only an "early access" in 4.1.0.
> IQ metadata reports non-existent partitions when a member owns a non-prefix
> task set of a subtopology with uneven source-topic partition counts: There is
> a Task T with two input topic A (5 partitions) and B (2 partitions). A member
> has tasks 0_1 and 0_3 assigned. For topic B, it should only report to host
> task 0_1 (because 0_3 has no B partition assigned), but it incorrectly
> reports to host both 0_1 and 0_3.
