Jesus Camacho Rodriguez commented on HIVE-15119:
------------------------------------------------
[~vgarg], there seem to be errors now that I did not see with the third patch.
I saw an additional rule in the parser, i.e., _groupByExpressions_. Maybe that
is the reason for those errors? I saw it is not referenced, why was it added?
Thanks

> Standard ROLLUP and CUBE syntax is GROUP BY ROLLUP (expression list)... and
> GROUP BY CUBE (expression list) respectively.
> Currently HIVE only allows GROUP BY <expression list> WITH ROLLUP/CUBE syntax.
>
> We would like HIVE to support standard ROLLUP/CUBE syntax.
