Abhishek Girish commented on DRILL-2317:
----------------------------------------
The issue isn't limited to sub-queries with single column projection:
{code:sql}
select x
from
(SELECT ss_ext_sales_price x, ss_item_sk w
FROM store_sales
UNION ALL
SELECT cs_ext_sales_price y, cs_item_sk v
FROM catalog_sales) tmp
GROUP BY x
LIMIT 10
;
Query failed: RemoteRpcException: Failure while running fragment., index: 0,
length: 1 (expected: range(0, 0)) [ b7e35c29-33e9-4e24-93a0-3c58d4233120 on
abhi5.qa.lab:31010 ]
[ b7e35c29-33e9-4e24-93a0-3c58d4233120 on abhi5.qa.lab:31010 ]
java.lang.RuntimeException: java.sql.SQLException: Failure while executing
query.

> A UNION ALL on two sub-queries with only a single column projected, and GROUP
> BY on the whole query fails with an IndexOutOfBoundsException
> *The following query fails to execute:*
> {code:sql}
> SELECT c1
> FROM ((SELECT ss_quantity AS c1
> FROM store_sales limit 1)
> UNION ALL
> (SELECT ws_quantity AS c2
> FROM web_sales limit 1)
> ) foo
> GROUP BY c1;
> {code}
> *The following query also fails to execute:*
> {code:sql}
> SELECT distinct(c)
> FROM ((SELECT ss_quantity AS c
> FROM store_sales limit 1)
> UNION ALL
> (SELECT ws_quantity AS c
> FROM web_sales limit 1)
> ) ;
> {code}
> Error:
> Query failed: RemoteRpcException: Failure while running fragment., index: 0,
