------------------------------------
Summary: KafkaClusterTestKit should support mixed-mode testing
Key: KAFKA-12501
URL: https://issues.apache.org/jira/browse/KAFKA-12501
Project: Kafka
Issue Type: Bug
Reporter: David Arthur
Follow-on from https://github.com/apache/kafka/pull/10220
We should allow for mixed-mode testing with TestKit. Currently, brokers and
controllers nodes are run in their respective modes only (where each has only
one process role).
It would be nice to allow for "mixed-mode" where one node has both the broker
and controller role. This would help us write tests that verify that all the
various listeners are working properly on a single node running both roles.
As [~hachikuji] [pointed
out|https://github.com/apache/kafka/pull/10220#discussion_r588571846], we could
probably eliminate some of the manual node building in the testkit code by
using KafkaRaftServer directly.
