@[~dongjoon] I am wondering if structured streaming works in a similar scenario.

> Maybe this is spark-shell specific and is not expected to work anyway, as I
> dont see this to be an issues with a normal jar.
> Note that with Spark 2.3.3 the error is different and this still does not
> work but with a different error.
