             Summary: Refactor and re-enable flink-sql-client-test E2E test
                 Key: FLINK-40048
                 URL: https://issues.apache.org/jira/browse/FLINK-40048
             Project: Flink
          Issue Type: Technical Debt
            Reporter: Martijn Visser


Triggered by https://github.com/apache/flink/pull/27924 I looked into the flink-sql-client-test. This module (flink-end-to-end-tests/flink-sql-client-test/) carries dead-weight Kafka dependencies:

1. flink-sql-connector-kafka:3.0.0-1.17 -> pinned to a Flink 1.17-era version of an externalized connector (removed from main repo in FLINK-30859)
2. kafka-clients:3.9.2 (test scope) -> only used by sendMessages(), which is only called from testMatchRecognize()
3. testcontainers-kafka (test scope) -> Kafka container only started for the disabled test

testMatchRecognize() has been @Disabled("Disable due to Kafka connector need to release a new version 2.0.") since the connector was externalized and has never been re-enabled. It is also the only E2E test for MATCH_RECOGNIZE in the entire repo.

I'd recommend to remove Kafka and re-enable this test using the filesystem source instead
