> The following query should not be allowed in Drill planner.
> {code}
> select * from cp.`tpch/nation.parquet` group by n_regionkey;
> +----+
> | * |
> +----+
> | 0 |
> | 1 |
> | 4 |
> | 3 |
> | 2 |

> {code}
> However, Drill allow such query to run and even worse the result is
> incorrect. It would make sense that we block such type of query.
