[jira] [Created] (DRILL-2161) Flatten on a list within a list on a
large data set results in an IOB Exception
Rahul Challapalli created DRILL-2161:
----------------------------------------
Summary: Flatten on a list within a list on a large data set results in an IOB Exception
Key: DRILL-2161
URL: https://issues.apache.org/jira/browse/DRILL-2161
Project: Apache Drill
Issue Type: Bug
Components: Execution - Flow, Execution - Relational Operators
Reporter: Rahul Challapalli
Assignee: Jason Altekruse
Attachments: data.json
git.commit.id.abbrev=3e33880
I attached the data set which contains 2 records.
Below query works fine on the attached data set
{code}
0: jdbc:drill:schema=dfs.drillTestDir> select uid, flatten(d.lst_lst) lst from `data.json` d;
+------------+------------+
| uid | lst |
+------------+------------+
| 1 | [1,2,3,4,5] |
| 1 | [2,3,4,5,6] |
| 2 | [1,2,3,4,5] |
| 2 | [2,3,4,5,6] |
+------------+------------+
{code}
However if I copy the same data set 50, 000 times, and run the same query, it fails with IOB. Below is the contents of the log file
{code}
