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
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:
