-------------------------------------

             Summary: Disable HadoppConf and Kerboros Decorator by default
                 Key: FLINK-30363
                 URL: https://issues.apache.org/jira/browse/FLINK-30363
             Project: Flink
          Issue Type: Improvement
          Components: Kubernetes Operator
    Affects Versions: kubernetes-operator-1.1.0
            Reporter: Zhenqiu Huang


Flink natively replies on these two decorator to create config maps and k8s secrets before creating job manager pod in K8s. It works well in job submisstion through Flink Cli.

org.apache.flink.kubernetes.kubeclient.decorators.HadoopConfMountDecorator
org.apache.flink.kubernetes.kubeclient.decorators.KerberosMountDecorator

But It doesn't work in operator mode:
1) Operator class path doesn't had HADOOP or Kerberos related info, so resources willn't be created.
2) When FlinkResourceManager create TM Pod. If JM POD has HADOOP env variables or Kerberos config are included application flink conf, then one of decorators will be enabled. TM Pod will mount on config maps or secrets that are not created yet.

Thus, we should help user to disable these two Decorators by default.
