Resolution: Fixed
> AlterPartition is not idempotent when requests time out
> -------------------------------------------------------
>
> Key: KAFKA-14144
> URL: https://issues.apache.org/jira/browse/KAFKA-14144
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 3.3.0
> Reporter: David Mao
> Assignee: David Mao
> Priority: Blocker
> Fix For: 3.3.0
>
>
> [https://github.com/apache/kafka/pull/12032] changed the validation order of
> AlterPartition requests to fence requests with a stale partition epoch before
> we compare the leader and ISR contents.
> This results in a loss of idempotency if a leader does not receive an
> AlterPartition response because retries will receive an
> INVALID_UPDATE_VERSION error.
