There are some messages needed to be updated too, e.g,:
| Spark standalone or Mesos with cluster deploy mode only:
| --supervise If given, restarts the driver on
failure.
| --kill SUBMISSION_ID If given, kills the driver specified.
| --status SUBMISSION_ID If given, requests the status of the
driver specified.
From above, k8s supports killing submission and requesting submission
statuses.
| Spark standalone and Mesos only:
| --total-executor-cores NUM Total cores for all executors.
k8s also supports `totalExecutorCores` option.
