Description

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
n.n_name,
sum(l.l_extendedprice * (1 - l.l_discount)) as revenue

from
customer c,
orders o,
lineitem l,
supplier s,
nation n,
region r

where
c.c_custkey = o.o_custkey
and l.l_orderkey = o.o_orderkey
and l.l_suppkey = s.s_suppkey
and c.c_nationkey = s.s_nationkey
and s.s_nationkey = n.n_nationkey
and n.n_regionkey = r.r_regionkey
and r.r_name = 'EUROPE'
and o.o_orderdate >= date '1997-01-01'
and o.o_orderdate < date '1997-01-01' + interval '1' year
group by
n.n_name

order by
revenue desc

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:
