> 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 `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` 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.
