The below query on top of tpch 0.01 data should actually return 0 records. (Verified with postgres). However drill returns incorrect result
{code}
select count(*) from cp.`tpch/lineitem.parquet` l inner join (select o.o_orderkey, o.o_custkey from cp.`tpch/orders.parquet` o where o.o_custkey < 5) s on l.l_orderkey = s.o_orderkey and s.o_custkey > 5;
+------------+
|   EXPR$0   |
+------------+
| 189        |
+------------+
{code}

Marked as 'critical' since drill is reporting incorrect results
