Chun Chang created DRILL-1745:
---------------------------------
Summary: order by a json array element caused
IndexOutOfBoundsException
Key: DRILL-1745
URL: https://issues.apache.org/jira/browse/DRILL-1745
Project: Apache Drill
Issue Type: Bug
Components: Storage - JSON
Affects Versions: 0.7.0
Reporter: Chun Chang
#Thu Nov 13 22:54:15 EST 2014
git.commit.id.abbrev=108d29f
JSON data has 1 million rows. The following query works:
0: jdbc:drill:schema=dfs> select t.gbyt, t.id from `complex.json` t order by
t.id limit 10;
+------------+------------+
| gbyt | id |
+------------+------------+
| soa | 1 |
| oooa | 2 |
| bool | 3 |
| nul | 4 |
| gbyi | 5 |
| bool | 6 |
| soa | 7 |
| bool | 8 |
| oooa | 9 |
| oooa | 10 |
+------------+------------+
10 rows selected (102.968 seconds)
But if I added the following element, it will cause the exception. Without
order by also works.
0: jdbc:drill:schema=dfs> select t.gbyt, t.id, t.ooa[0].`in` zeroin from
`complex.json` t order by t.id limit 10;
+------------+------------+------------+
| gbyt | id | zeroin |
+------------+------------+------------+
