------------------------------------
> Are you sure on these?
I am almost sure we can fix Parquet and Kafka related warnings. Not sure about
warnings coming from deprecated Spark API. Maybe it is possible to suppress
such warnings in tests. In any case, we know in advance that we test deprecated
API. Such warnings don't guard us from mistakes.
I quickly googled and found this
[https://github.com/scala/bug/issues/7934#issuecomment-292425679] . Maybe we
can use the approach in tests.
