Description

I deployed basic-example job using flink-kubernetes-operator(v1.5.0) and flink (v1.17.1)

I do not need to mount kerberos (keytab), so I set kubernetes.decorator.kerberos-mount.enabled as false

And checked that above option set as false in log of job manager and task manager.

 

Then as I understand, when kubernetes.decorator.kerberos-mount.enabled is false, it should not create secret.
(https://github.com/apache/flink/blob/2750d5c26b1ff8e3706a7c0d7cb2c8955247f538/flink-kubernetes/src/main/java/org/apache/flink/kubernetes/kubeclient/factory/KubernetesJobManagerFactory.java#L83-L95)

But It create secret kerberos-keytab-basic-example
