Subject [jira] [Commented] (DRILL-617) TPCH: query 14 verification fails
Date Thu, 29 May 2014 16:59:04 GMT

Jacques Nadeau commented on DRILL-617:
--------------------------------------

Spot manual verifications shows correct results other than floating point variations with
latest master.  Please update verification framework to correctly identify these.

>                 URL: https://issues.apache.org/jira/browse/DRILL-617
>             Project: Apache Drill
>          Issue Type: Bug
>            Reporter: Zhiyong Liu
>            Priority: Blocker
>
> 1. Set up drill test framework (see https://github.com/zhiyongliu/incubator-drill/tree/master/testing)
and generate TCP H dataset with a scale factor of about 500MB.
> 2. Query file (modified from original by drill dev, and further modified as follows):
> select
>   100.00 * sum(case
>     when p.p_type like 'PROMO%'
>       then l.l_extendedprice * (1 - l.l_discount)
>     else 0
>   end) / sum(l.l_extendedprice * (1 - l.l_discount)) as promo_revenue
> from
>   lineitem l,
>   part p
> where
>   l.l_partkey = p.p_partkey
>   and l.l_shipdate >= date '1994-08-01'
>   and l.l_shipdate < date '1994-08-01' + interval '1' month;
> 3. Drill build:
> git.commit.id=1e0e4dfc96c8e7eb83659784dfbb85cd83d7d243
> 4. The baseline/expected results are generated via Oracle DB.
> 5. Run the above query in the test framework, with verification turned on.
> 6. Verification fails:
