Jesus Camacho Rodriguez commented on CALCITE-542:
-------------------------------------------------
Thanks! I just changed the line according to your review. I also added a test
(RelMdColumnOriginsTest) based on the query that was producing the problem in
Hive: the test does not pass, but I think the problem is not related to
RelMdColumnOrigins (is it a problem related to the data type of the
{{grouping(col)}} column?).

> When we call {{getColumnOrigins}} on an {{Aggregate}} operator with grouping
> sets, an error arrises if we are trying to derive the origin of an indicator
> column associated to a grouping column.
