Alan Gates updated HIVE-4193:
-----------------------------
Attachment: Range_5_diff
A diff from last night's run for the query:
select i, f, avg(d) over (partition by i order by f desc rows between 5
preceding and 5 following) from over100k;
Based on the output this doesn't look like a sort stability issue.
> OVER clauses with BETWEEN in the window definition produce wrong results

> Project: Hive
> Issue Type: Bug
> Components: PTF-Windowing
> Affects Versions: 0.11.0
> Reporter: Alan Gates
> Attachments: Range_5_diff
>
>
> 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}
