             Summary: OVER clauses with BETWEEN in the window definition produce wrong results
                 Key: HIVE-4193
                 URL: https://issues.apache.org/jira/browse/HIVE-4193
             Project: Hive
          Issue Type: Bug
          Components: PTF-Windowing
    Affects Versions: 0.11.0
            Reporter: Alan Gates


Window queries that define a windowing clause that has a termination row often (though not all) return incorrect results.  For example, from our test queries all of the following return incorrect results:

{code}
select s, sum(f) over (partition by t order by b 
       rows between current row and unbounded following) 
from over100k;

select s, avg(f) over (partition by b order by d 
       rows between 5 preceding and current row) 
from over100k;

select s, avg(f) over (partition by bin order by s 
       rows between current row and 5 following) 
from over100k;

select s, avg(d) over (partition by i order by f desc 
       rows between 5 preceding and 5 following) 
from over100k;
{code}
