> The HiveRelBuilder overrides
> [aggregateCall|https://github.com/apache/hive/blob/8c3567ea8e423b202cde370f4d3fb401bcc23e46/ql/src/java/org/apache/hadoop/hive/ql/optimizer/calcite/HiveRelBuilder.java#L246]
> from its superclass simply to expose and use it in
> HiveRewriteToDataSketchesRules.
> However, there is no real need to override this method since we can achieve
> the same outcome by using existing methods in RelBuilder which are easier to
> use and understand. Furthermore it is safer to depend on public APIs since
> are more stable in general.
