> https://issues.apache.org/jira/browse/SPARK-47199 didn't fix the flakiness in
> the pyspark.sql.dataframe.DataFrame.writeStream doctest : the problem is not
> that we are colliding on the test but, rather, that the test is starting a
> background thread to write to a directory then deleting that directory from
> the main test thread, something which is inherently race prone.
> The fix is simple: stop the streaming query in the doctest itself, similar to
> other streaming doctest examples.
