@fhueske Thank you for the detailed review! I've updated my code according
to your comments.
I noticed that @wuchong is performing some type conversions in his
INTERSECT implementation:
https://github.com/apache/flink/pull/2159/files#diff-a6c2112ca46d26fcf49f1edba1c73f75R121
Should I do something similar in the EXCEPT case? If yes, does it mean that
my test coverage is not sufficient and does not cover some particular case?
