--------------------------------------
Summary: Update static membership fencing system test to support
new protocol
Key: KAFKA-16566
URL: https://issues.apache.org/jira/browse/KAFKA-16566
Project: Kafka
Issue Type: Bug
Affects Versions: 3.7.0
Reporter: Lianet Magrans
Assignee: Lianet Magrans
Fix For: 3.8.0
consumer_test.py contains OffsetValidationTest.test_fencing_static_consumer
that verifies the sequence in which static members join a group when using
conflicting instance id. This behaviour is different in the classic and
consumer protocol, so the tests should be updated to set the right expectations
when running with the new consumer protocol. Note that what the tests covers
(params, setup), apply to both protocols. It is the expected results that are
not the same.
When conflicts between static members joining a group:
Classic protocol: all members join the group with the same group instance id,
and then the first one will eventually receive a HB error with
FencedInstanceIdException
Consumer protocol: new member with an instance Id already in use is not able to
join, receiving an UnreleasedInstanceIdException in the response to the HB to
join the group.
