git.commit.id.abbrev=e5c2da0
The below query results in 0 results being returned
select count(*) from `lineitem1.parquet` a
inner join `part.parquet` j on a.l_partkey = j.p_partkey
inner join `orders.parquet` k on a.l_orderkey = k.o_orderkey
inner join `supplier.parquet` l on a.l_suppkey = l.s_suppkey
inner join `partsupp.parquet` m on j.p_partkey = m.ps_partkey and l.s_suppkey =
m.ps_suppkey
inner join `customer.parquet` n on k.o_custkey = n.c_custkey
inner join `lineitem2.parquet` b on a.l_orderkey = b.l_orderkey
inner join `lineitem2.parquet` c on a.l_partkey = c.l_partkey
inner join `lineitem2.parquet` d on a.l_suppkey = d.l_suppkey
inner join `lineitem2.parquet` e on a.l_extendedprice = e.l_extendedprice
inner join `lineitem2.parquet` f on a.l_comment = f.l_comment
inner join `lineitem2.parquet` g on a.l_shipdate = g.l_shipdate
inner join `lineitem2.parquet` h on a.l_commitdate = h.l_commitdate
inner join `lineitem2.parquet` i on a.l_receiptdate = i.l_receiptdate
inner join `lineitem2.parquet` o on a.l_receiptdate = o.l_receiptdate
inner join `lineitem2.parquet` p on a.l_receiptdate = p.l_receiptdate
inner join `lineitem2.parquet` q on a.l_receiptdate = q.l_receiptdate
inner join `lineitem2.parquet` r on a.l_receiptdate = r.l_receiptdate
inner join `lineitem2.parquet` s on a.l_receiptdate = s.l_receiptdate
inner join `lineitem2.parquet` t on a.l_receiptdate = t.l_receiptdate
inner join `lineitem2.parquet` u on a.l_receiptdate = u.l_receiptdate
inner join `lineitem2.parquet` v on a.l_receiptdate = v.l_receiptdate
inner join `lineitem2.parquet` w on a.l_receiptdate = w.l_receiptdate
inner join `lineitem2.parquet` x on a.l_receiptdate = x.l_receiptdate;
However when we remove the last 'inner join' and run the query it returns
'716372534'. Since the last inner join is similar to the one's before it, it
should match some records and return the data appropriately.
The logs indicated that it actually returned 0 results. Attached the log file.
