  Jobs that are tracked using this mechanism get the annotation `batch.kubernetes.io/job-tracking`. This is a temporary measure. Two releases after this feature graduates to beta, the annotation won't be added to Jobs anymore.

    begin a graceful deletion and wait until the resource is fully deleted.  To force
    deletion immediately, use the `--force` flag. This prevents users from accidentally
    allowing two Stateful Set pods to share the same persistent volume which could lead to data
    corruption [#37263](https://github.com/kubernetes/kubernetes/pull/37263)
