Hello, Sometimes I see job manager getting restarted because of following exceptions in our flink cluster (managed by flink k8s operator). Is this intermittent issue or something we need to tune job manager with ?

2023-01-19 02:04:13,975 ERROR io.fabric8.kubernetes.client.extended.leaderelection.LeaderElector [] - Exception occurred while acquiring lock 'ConfigMapLock: streaming-application streaming-application-resourcemanager-leader (dc2d523f-ffba-493c-9192-e0e4ddc8d299)'

io.fabric8.kubernetes.client.KubernetesClientException: Operation: [get]  for kind: [ConfigMap]  with name: [streaming-application-resourcemanager-leader]  in namespace: [streaming-application]  failed.

at io.fabric8.kubernetes.client.KubernetesClientException.launderThrowable(KubernetesClientException.java:64) ~[flink-dist_2.12-1.13.6.jar:1.13.6]

I would recommend upgrading to a newer, still community supported version of Flink. Many improvements have happened in the last 3 years releases

Thanks for responding
