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
[Error Id: e7d7df50-c5e8-4eda-990a-050b9a2b188e on qa-node190.qa.lab:31010]
(state=,code=0)
{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 '*'
File Path maprfs:///drill/testdata/temp.tbl
Fragment 0:0
[Error Id: 1856f171-966e-4078-bbea-7ff3e9e22e15 on qa-node190.qa.lab:31010]

{code}
A similar query against json and parquet seems to be working fine
{code}
select current_date from `a.json` group by current_date;
+---------------+
| current_date |
+---------------+
| 2015-09-14 |
+---------------+
select CURRENT_DATE from cp.`tpch/lineitem.parquet` group by CURRENT_DATE;
+---------------+
| CURRENT_DATE |
+---------------+
| 2015-09-14 |
+---------------+
{code}
I attached the log files for the failing conditions. Let me know if you need
anything
