Query fails with schema change error, even though there isn't any:
{code:sql}
select x
from
(SELECT Sum(ss_ext_sales_price) x
FROM store_sales
UNION ALL
SELECT Sum(cs_ext_sales_price) y
FROM catalog_sales) tmp
GROUP BY x
ORDER BY x;
+------------+
| x |
+------------+
Query failed: SYSTEM ERROR: Hash aggregate does not support schema changes

Query with explicit cast on sum() works:
{code:sql}
SELECT x
FROM
(SELECT cast (Sum(s.ss_ext_sales_price) as double) x
FROM store_sales s
UNION ALL
SELECT cast(Sum(c.cs_ext_sales_price) as double) y
FROM catalog_sales c) tmp
GROUP BY x
ORDER BY x;
