> Using CURRENT_DATE in a group by seems to failing against hive and csv files. With parquet and json, there seems to be no issues.
> Query against a hive table :
> {code}
> select CURRENT_DATE from student_hive group by CURRENT_DATE;
> Error: PARSE ERROR: From line 1, column 48 to line 1, column 59: Column 'CURRENT_DATE' not found in any table

> {code}
> Query against csv files :
> {code}
> select CURRENT_DATE from `temp.tbl` group by CURRENT_DATE;
> Error: DATA_READ ERROR: Selected column 'CURRENT_DATE' must have name 'columns' or must be plain '*'

> A similar query against json and parquet seems to be working fine
> {code}
> select current_date from `a.json` group by current_date;
