The change looks great overall.
I tested this branch in my Kubernetes environment and I'm getting an error
when running a paragraph.
```

Although my environment has a [slight
modification](https://github.com/open-datastudio/zeppelin/blob/master-snapshot/.staroid/k8s/100-interpreter-spec.yaml)
on `k8s/100-interpreter-spec.yaml` but the modification does not change
`metadata.name` field.
`kubectl` based code works without error against the same resource file.
Is there any place I can check?
