Subject [jira] [Commented] (DRILL-616) TPCH: query 12 verification fails
Date Thu, 29 May 2014 16:59:04 GMT

Jacques Nadeau commented on DRILL-616:
--------------------------------------

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-616
>             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
>   l.l_shipmode,
>   sum(case
>     when o.o_orderpriority = '1-URGENT'
>       or o.o_orderpriority = '2-HIGH'
>       then 1
>     else 0
>   end) as high_line_count,
>   sum(case
>     when o.o_orderpriority <> '1-URGENT'
>       and o.o_orderpriority <> '2-HIGH'
>       then 1
>     else 0
>   end) as low_line_count
> from
>   orders o,
>   lineitem l
> where
>   o.o_orderkey = l.l_orderkey
>   and l.l_shipmode in ('TRUCK', 'REG AIR')
>   and l.l_commitdate < l.l_receiptdate
>   and l.l_shipdate < l.l_commitdate
>   and l.l_receiptdate >= date '1994-01-01'
>   and l.l_receiptdate < date '1994-01-01' + interval '1' year
> group by
>   l.l_shipmode
> order by
>   l.l_shipmode;
> 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:
