--------------------------------------
I have a working patch. Will raise a PR sooner.
> Enable debug package feature on structured streaming
> ----------------------------------------------------
>
> Key: SPARK-24161
> URL: https://issues.apache.org/jira/browse/SPARK-24161
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 2.3.0
> Reporter: Jungtaek Lim
> Priority: Major
>
> Currently, debug package has a implicit class which matches Dataset to
> provide debug features on Dataset class. It doesn't work with structured
> streaming: it requires query is already started, and the information can be
> retrieved from StreamingQuery, not Dataset. For the same reason, "explain"
> had to be placed to StreamingQuery whereas it exists on Dataset.
> This issue tracks effort to enable debug package feature on structured
> streaming. Unlike batch, it may have some restrictions.
