Even in the impersonation mode, it is the process owner to interrupt the
process. Here it is the interpreter process owner interrupt the process instead
of the zeppelin server owner. But I can not verify it in impersonation mode.
It seems the impersonation mode is broken. I got the following error, can
anyone else verify the impersonation mode ?
```
