Martijn Visser commented on FLINK-34415:
----------------------------------------
[~taranpreet] The connector tests moved to KRaft in FLINK-38937, and in Flink
itself FLINK-38809 switched the last KafkaContainer to ConfluentKafkaContainer
and FLINK-40048 removed Kafka from that test. Closing as duplicate of
FLINK-38937. The Zookeeper based Kafka left in
flink-end-to-end-tests/test-scripts is only used by the Avro Confluent Schema
Registry test, which is disabled and tracked in FLINK-36268.

> The current Flink Kafka connector still uses Zookeeper for Kafka-based
> testing. Since Kafka 3.3, KRaft has been marked as production ready [1]. In
> order to reduce tech debt, we should remove all the dependencies on Zookeeper
> and only uses KRaft for the Flink Kafka connector.
