Sungwoo Park commented on HIVE-26655:
-------------------------------------
This case is a bit different because the query is completed successfully but
with wrong results, which is worse than failing to compile or finish the query.
I think users often run queries without computing statistics, e.g., because
they forget to compute statistics or because they use text datasets, and so on.
> TPC-DS query 17 returns wrong results

> When tested with 100GB ORC tables, the number of rows returned by query 17 is
> not stable. It returns fewer rows than the correct result (55 rows).
