Matthias Pohl commented on FLINK-34333:
---------------------------------------
I think it's fine to do the upgrade from v6.6.2 to v6.9.0 even for 1.18:
* The only change that seems to affect Flink is in the Mock-framework and only
affects test code
* Most of the changes are cleanup changes, except for:
** Fix [#5262|https://github.com/fabric8io/kubernetes-client/issues/5262]:
Changed behavior in certain scenarios
** Fix [#5125|https://github.com/fabric8io/kubernetes-client/issues/5125]:
Different default TLS version
** Fix [#1335|https://github.com/fabric8io/kubernetes-client/issues/1335]:
Different fallback used for proxy configuration
Generally, we could argue that downstream project should rely on transitive
dependencies provided by Flink. And fixing the bug out-weighs the stability
concerns here. Do you see a problem with this argument [~gyfora],
[~wangyang0918]?
The alternatives to doing the upgrade are:
* Reverting the upgrade (i.e. going back from v6.6.2 to v5.12.4). This would
allow us to get to the stable version that was tested with 1.17-
* Provide a Flink-customized implementation of the fabric8io {{LeaderElector}}
class with the cherry-picked changes of
[8f8c438f|https://github.com/fabric8io/kubernetes-client/commit/8f8c438f] and
[0f6c6965|https://github.com/fabric8io/kubernetes-client/commit/0f6c6965]. As a
consequence, we would stick to fabric8io:kubernetes-client v.6.6.2

> FLINK-34007 revealed a bug in the k8s client v6.6.2 which we're using since
> Flink 1.18. This issue was fixed with FLINK-34007 for Flink 1.19 which
> required an update of the k8s client to v6.9.0.
> This Jira issue is about finding a solution in Flink 1.18 for the very same
> problem FLINK-34007 covered. It's a dedicated Jira issue because we want to
> unblock the release of 1.19 by resolving FLINK-34007.
