Project: Apache Drill
Issue Type: Bug
Reporter: Zhiyong Liu
1. Create TCP H dataset with a scale factor of about 500MB.
2. Run the following query in sqlline:
select
c.c_name,
c.c_custkey,
o.o_orderkey,
o.o_orderdate,
o.o_totalprice,
sum(l.l_quantity)
from
customer c,
orders o,
lineitem l
where
o.o_orderkey in (
select
l_orderkey
from
lineitem
group by
l_orderkey having
sum(l_quantity) > 300
)
and c.c_custkey = o.o_custkey
and o.o_orderkey = l.l_orderkey
group by
c.c_name,
c.c_custkey,
o.o_orderkey,
o.o_orderdate,
o.o_totalprice
order by
o.o_totalprice desc,
o.o_orderdate;
The following exception is encountered:
Query failed: org.apache.drill.exec.rpc.RpcException: Remote failure while

In contrast, if this data source is used:
http://apache-drill.s3.amazonaws.com/files/sf-0.01_tpc-h_parquet.tgz
then query went through successfully.
