Jesus Camacho Rodriguez commented on HIVE-20781:
------------------------------------------------
[~kgyrtkirk], can you provide more context? Is retType incorrect? Calcite and
Hive may have different ways of inferring return type for expressions, hence I
believe it would be safer to fix retType rather than not specifying it.
> Don't set type for CASE statements during Rex translation
