Sudheesh Katkam commented on DRILL-2288:
----------------------------------------
Here's another test case:
Create an empty hive table. And then:
{code}
0: jdbc:drill:> select * from hive.nation;
+--+
| |
+--+
+--+
No rows selected (0.789 seconds)
{code}
However,
{code}
0: jdbc:drill:> SELECT COLUMN_NAME, DATA_TYPE FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'nation' AND TABLE_SCHEMA = 'hive.default';
+--------------+--------------------+
| COLUMN_NAME | DATA_TYPE |
+--------------+--------------------+
| n_nationkey | INTEGER |
| n_name | CHARACTER VARYING |
| n_regionkey | INTEGER |
| n_comment | CHARACTER VARYING |
+--------------+--------------------+
4 rows selected (10.363 seconds)
{code}
> ResultSetMetaData not set for zero-row results
> (DatabaseMetaData.getColumns(...)) [ScanBatch problem]
