Description:
Support for standard
{code:java}
GROUP BY { group_expression |
{ ROLLUP | CUBE | GROUPING SETS }
(grouping_set [ , ...]) } [ , ... ] {code}
syntax was added to Spark several releases ago in addition to the previously
supported non-standard syntax
{code:java}
GROUP BY group_expression [ , group_expression [ , ... ] ] [ WITH { ROLLUP |
CUBE } ] {code}
See:
[https://spark.apache.org/docs/latest/sql-ref-syntax-qry-select-groupby.html]
