------------------------------------
Summary: Upgrade Zk to 3.8.1
Key: KAFKA-14661
URL: https://issues.apache.org/jira/browse/KAFKA-14661
Project: Kafka
Issue Type: Bug
Components: zkclient
Reporter: Divij Vaidya
Assignee: Christo Lolov
Fix For: 3.5.0, 3.4.1, 3.3.3
Current Zk version (3.6.x) supported by Apache Kafka has been EOL since
December 2022 [1]
Users of Kafka are facing regulatory hurdles because of using a dependency
which is EOL, hence, I would suggest to upgrade this in all upcoming releases
(including patch releases of 3.3.x and 3.4.x versions).
Some things to consider while upgrading (as pointed by [~ijuma] at [2]):
# If we upgrade the zk server to 3.8.1, what is the impact on the zk clients.
That is, what's the earliest zk client version that is supported by the 3.8.x
server?
# We need to ensure there are no regressions (particularly on the stability
front) when it comes to this upgrade. It would be good for someone to stress
test the system a bit with the new version and check if all works well.
