-------------------------------------------------------------
With Knox in the cluster with ZooKeeper, the ZooKeeper interactions are much
more responsive. When a request is made to delete a provider config, Knox (if
configured for remote config monitoring) will delete the remote record, then
subsequently delete the local file. In this case, Knox receives the
notification of the remote deletion before it attempts to delete the local
file. When the local file deletion is attempted, it fails because it no longer
exists (because the remote notification has already triggered the local
deletion), and the API reports that it could not be deleted.
