> In Calcite, it is not necessary that the columns in the group set are in the
> same order as the rollup. For instance, this is the Calcite representation of
> a rollup for a given query:
> {code}
> HiveAggregate(group=[{1, 6, 7}], groups=[[{1, 6, 7}, {1, 7}, {1}, {}]],
> agg#0=[sum($12)], agg#1=[count($12)], agg#2=[sum($4)], agg#3=[count($4)],
> agg#4=[sum($15)], agg#5=[count($15)])
> {code}
> When we generate the Hive plan from the Calcite operator, we make such
> assumption incorrectly.
