-------------------------------

             Summary: Improve windowing_windowspec2.q tests to return consistent results
                 Key: HIVE-11962
                 URL: https://issues.apache.org/jira/browse/HIVE-11962
             Project: Hive
          Issue Type: Test
          Components: Test
    Affects Versions: 2.0.0
            Reporter: Aihua Xu
            Priority: Trivial


Upstream test result for windowing_windowspec2.q seems to return consistent result while we
have observe that in a different test env, the result could be slightly different. 
e.g., for the following query, the value t could be the same in each partition of ts. So the
row order could be either for those rows. I haven't looked further why it causes that difference
yet.

{noformat} 
select ts, f, max(f) over (partition by ts order by t rows between 2 preceding and 1 preceding)
from over10k limit 100;
{noformat}
