Key: HIVE-26627

Project: Hive
Issue Type: Task
Components: CBO
Reporter: Stamatis Zampetakis

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.
