             Summary: Order by on a repeated index from the output of a flatten on large no of records results in incorrect results
                 Key: DRILL-2167
                 URL: https://issues.apache.org/jira/browse/DRILL-2167
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Rahul Challapalli
            Assignee: Jason Altekruse
            Priority: Critical
         Attachments: data.json

git.commit.id.abbrev=3e33880

The below query results in 200006 records. Based on the data set we should only receive 200000 records. 
{code}
select s.uid from (select d.uid, flatten(d.map.rm) rms from `data.json` d) s order by s.rms.rptd[1].d;
{code}

When I removed the order by part, drill correctly reported 200000 records.
{code}
select s.uid from (select d.uid, flatten(d.map.rm) rms from `data.json` d) s;
{code}


I attached the data set with 2 records. I copied over the data set 50000 times and ran the queries on top of it. Let me know if you have any other questions
