[jira] [Created] (DRILL-2095) Order by on a repeated index inside a
sub query results in an NPE
Rahul Challapalli created DRILL-2095:
----------------------------------------
Summary: Order by on a repeated index inside a sub query results in an NPE
Key: DRILL-2095
URL: https://issues.apache.org/jira/browse/DRILL-2095
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Reporter: Rahul Challapalli
Assignee: Jinfeng Ni
Priority: Critical
git.commit.id.abbrev=3e33880
Data Set :
{code}
{
"id" : 1,
"list" : [1,2]
}
{code}
The below query succeeds
{code}
0: jdbc:drill:schema=dfs.drillTestDir> select d.id id from `data.json` d order by d.list[0];
+------------+
| id |
+------------+
| 1 |
+------------+
1 row selected (0.12 seconds)
{code}
However when we use the same query inside a sub-query we get an NPE
{code}
0: jdbc:drill:schema=dfs.drillTestDir> select s.id from (select d.id id from `data.json` d order by d.list[0]) s;
Query failed: NullPointerException:
Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}
Explain plan also results in the same NPE for the above query
