Ryan Skraba commented on BEAM-5164:
-----------------------------------
Thanks for the link for the context! Is it possible that de-shading of parquet
was a mistake?
>From the discussion, it sounds like (1) we should shade to prevent transitive

Is that about right?
Specifically for Spark, it looks like this is reported at least since 2.12.0
for versions of Spark < 2.4 -- it looks like ParquetIOIT should be OK as-is
with 2.4.3. I couldn't find any references to older versions of spark in the
code. [~ŁukaszG] Were you running with your own spark installation?
