[jira] [Commented] (FLINK-28481) Bump the fabric8 kubernetes-client to 5.12.3

    [ https://issues.apache.org/jira/browse/FLINK-28481?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17567179#comment-17567179 ] 

Yun Tang commented on FLINK-28481:
----------------------------------

From the implementation of [LeaderElector#renew|https://github.com/fabric8io/kubernetes-client/blob/v4.9.2/kubernetes-client/src/main/java/io/fabric8/kubernetes/client/extended/leaderelection/LeaderElector.java#L118-L125] at 4.9.2 version. I think this bug also exists for flink-1.13, right?

> The current fabric8 kubernetes-client(5.5.0) will swallow the {{KubernetesClientException}} and then the next renewing could not work properly until reach the deadline. This will be a serious problem because one time failure of renewing leader annotation will cause leadership lost.
