--------------------------------------
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.
