-------------------------------------
Summary: Extend TestSecurityRollingUpgrade system test to KRaft
Key: KAFKA-12799
URL: https://issues.apache.org/jira/browse/KAFKA-12799
Project: Kafka
Issue Type: Test
Components: system tests
Reporter: Ron Dagostino
The TestSecurityRollingUpgrade system test rolls Kafka brokers multiple times
to adjust listeners/inter-broker listeners while confirming that producers and
consumers continue to work throughout the multiple rolls. We need to extend
this test (or write a new one) that does something similar for the KRaft
controllers. Producers/consumers are perhaps less appropriate in such a case
-- maybe we need to create a topic after each roll to make sure the metalog is
being consumed correctly?
Note that this will require some logic in `KafkaService.security_config()`
because we cache the security config and we will have to mutate it to get the
changes to occur. See https://github.com/apache/kafka/pull/10694/ for what we
had to do for Kafka broker changes; something similar will have to happen for
controller changes.
