[jira] [Created] (FLINK-10838) Rewrite Kafka tests that fail Kafka brokers

Piotr Nowojski created FLINK-10838:
--------------------------------------

             Summary: Rewrite Kafka tests that fail Kafka brokers
                 Key: FLINK-10838
                 URL: https://issues.apache.org/jira/browse/FLINK-10838
             Project: Flink
          Issue Type: Improvement
          Components: Kafka Connector
    Affects Versions: 1.7.0
            Reporter: Piotr Nowojski


Currently we have many tests that in order to test for example `at-least-once`, they fail Kafka brokers, or brake network connection to them. It seems that those tests are more testing Kafka brokers then our own code and in the process (because of bugs in Kafka) cause lots of false positive results.

We could try to rewrite those tests to spawn one of the Flink's Task Managers in separate process and instead of failing network/kafka broker we could SIGKILL Task Manager, without touching/affecting Zookeeper/Kafka brokers. It should improve stability of our tests.
