Philip Nee resolved KAFKA-16579.
--------------------------------
Resolution: Fixed
> Revert changes to consumer_rolling_upgrade_test.py for the new async Consumer
> -----------------------------------------------------------------------------
>
> Key: KAFKA-16579
> URL: https://issues.apache.org/jira/browse/KAFKA-16579
> Project: Kafka
> Issue Type: Task
> Components: clients, consumer, system tests
> Affects Versions: 3.8.0
> Reporter: Kirk True
> Assignee: Philip Nee
> Priority: Critical
> Labels: kip-848-client-support, system-tests
> Fix For: 3.8.0
>
>
> To test the new, asynchronous Kafka {{Consumer}} implementation, we migrated
> a slew of system tests to run both the "old" and "new" implementations.
> KAFKA-16271 updated the system tests in {{consumer_rolling_upgrade_test.py}}
> so it could test the new consumer. However, the test is tailored specifically
> to the "old" Consumer's protocol and assignment strategy upgrade.
> Unsurprisingly, when we run those system tests with the new
> {{AsyncKafkaConsumer}}, we get errors like the following:
> {code}
> test_id:
> kafkatest.tests.client.consumer_rolling_upgrade_test.ConsumerRollingUpgradeTest.rolling_update_test.metadata_quorum=ISOLATED_KRAFT.use_new_coordinator=True.group_protocol=consumer
