Summary: Fix flaky system test
TestSecurityRollingUpgrade.test_enable_separate_interbroker_listener
Key: KAFKA-9797
URL: https://issues.apache.org/jira/browse/KAFKA-9797
Project: Kafka
Issue Type: Bug
Components: system tests
Reporter: Rajini Sivaram
Assignee: Rajini Sivaram
Fix For: 2.6.0
TestSecurityRollingUpgrade.test_enable_separate_interbroker_listener is
supposed to test non-disruptive upgrade of inter-broker listener using rolling
bounce. But the test updates inter-broker listener without enabling the new
listener/security_protocol across all brokers, making this a disruptive upgrade
where brokers are in inconsistent state until all brokers have been upgraded.
The test must first enable the new listener across all brokers and then update
the inter-broker listener to the new listener to ensure that the cluster is
functioning during the upgrade.
