Dawid Wysakowicz commented on FLINK-13702:
------------------------------------------
I don't know exactly how the {{JoinedRow}} is used and therefore if the
{{equals/hashCode}} is needed. Correct me if I am wrong but if we remove the
{{equals/hashCode}} from {{BinaryGeneric}}, doesn't it mean that we can no
longer use generic objects in a {{GroupBy}} clause, no? Isn't that a regression?
