> 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.
