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

             Summary: TPCH: query 14 verification fails
                 Key: DRILL-617
                 URL: https://issues.apache.org/jira/browse/DRILL-617
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Zhiyong Liu


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:
