[jira] [Created] (KAFKA-14661) Upgrade Zk to 3.8.1

Divij Vaidya created KAFKA-14661:
------------------------------------

             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.
