> Error encountered near token"
> Problem:
> ========
> A Hive query in a view which fails with the following error:
> Error while compiling statement: FAILED: SemanticException 35:21 [Error
> 10213]: Grouping sets expression is not in GROUP BY key. Error encountered
> near token 'l0_equities_region_id'
> Reproduction case:
> {noformat}
> create database test;
> create table test.case665558 (c1 string, c2 string);
> -- Working query
> select
> case
> when GROUPING__ID = 255 then `c1`
> end as `col_1`,
> case
> when GROUPING__ID = 255 then 3
> end as `col_2`,
> `c1`,
> `c2`
> from
> `test`.`case665558`
> group by
> `c1`,
> `c2`
> GROUPING SETS
> (
> (`c1`),
> (`c1`, `c2`)
> );
>
> create view test.viewcase665558

> select
> case
> when GROUPING__ID = 255 then `c1`

> Select * from test.viewcase665558 ;
> Error: Error while compiling statement: FAILED: SemanticException 17:1 [Error
> 10213]: Grouping sets expression is not in GROUP BY key. Error encountered
> near token 'c1' (state=42000,code=40000)
> {noformat}
> The issue is because when the view is created, it adds the name of the table
> to the columns. This seems to be confusing Hive:
> {noformat}
