    @mcgilman very cool to have this making its way into NiFi! I did some testing, and things work well for the most part. However, I did hit a NPE when running in non-cluster mode:
    
    ```

    Looks like the resource is calling getClusterCoordinator() and not expecting a 'null' to be returned. But in standalone mode, there's no Cluster Coordinator.
