> Project: Kafka
> Issue Type: Bug

> Affects Versions: 3.5.0
> Reporter: li xiangyuan
> Assignee: li xiangyuan
> Priority: Major
> Fix For: 3.8.0, 3.7.1
>
>
> AbstractStickyAssignor use ConstrainedAssignmentBuilder to build assignment
> when all consumers in group subscribe the same topic list, but it couldn't
> add all partitions move owner to another consumer to
> ``partitionsWithMultiplePreviousOwners``.
>
> the reason is in function assignOwnedPartitions hasn't add partitions that
> rack-mismatch with prev owner to allRevokedPartitions, then partition only in
> this list would add to partitionsWithMultiplePreviousOwners.
>
> In Cooperative Rebalance, partitions have changed owner must be removed from
> final assignment or will lead to incorrect consume behavior, I have already
> raise a pr, please take a look, thx
