Matthias Pohl updated FLINK-34333:
----------------------------------
Description:
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.
Just to summarize why the upgrade to v6.9.0 is desired: There's a bug in v6.6.2
which might prevent the leadership lost event being forwarded to the client
([#5463|https://github.com/fabric8io/kubernetes-client/issues/5463]). An
initial proposal where the release call was handled in Flink's
{{KubernetesLeaderElector}} didn't work due to the leadership lost event being
triggered twice (see [FLINK-34007 PR
comment|https://github.com/apache/flink/pull/24132#discussion_r1467175902])
