-------------------------------------
Summary: Making ZK-related logs available in tests
Key: FLINK-26223
URL: https://issues.apache.org/jira/browse/FLINK-26223
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination
Affects Versions: 1.15.0, 1.16.0
Reporter: Matthias Pohl
Recently, we had a few incidents where it appears that ZooKeeper wasn't
behaving as expected. It might help to have to the ZooKeeper logs available in
these cases.
We have multiple options:
* Introduce an extension to change the ZK log level for specific tests
* Lower the ZK log level again and make the logs being written to the standard
log files
* Lower the ZK log level again and move the ZK logs into a dedicated file to
avoid spoiling the Flink logs
