> If a grouping key hasn't been selected, Hive complains. For comparison, Postgres does
not.
> Example. Notice i_item_id is not selected:

> select  i_item_desc
>        ,i_category
>        ,i_class
>        ,i_current_price
>        ,sum(cs_ext_sales_price) as itemrevenue
>        ,sum(cs_ext_sales_price)*100/sum(sum(cs_ext_sales_price)) over
>            (partition by i_class) as revenueratio
>  from	catalog_sales
>      ,item
>      ,date_dim
>  where cs_item_sk = i_item_sk
>    and i_category in ('Jewelry', 'Sports', 'Books')
>    and cs_sold_date_sk = d_date_sk
>  and d_date between cast('2001-01-12' as date)
>  				and (cast('2001-01-12' as date) + 30 days)
>  group by i_item_id
>          ,i_item_desc
>          ,i_category
>          ,i_class
>          ,i_current_price
