----------------------------------------
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
