----------------------------------------------
Summary: Incorrect translation of rollup expression from Calcite
Key: HIVE-24232
URL: https://issues.apache.org/jira/browse/HIVE-24232
Project: Hive
Issue Type: Bug
Components: CBO
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
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.
