Rahul Challapalli created DRILL-1660:
----------------------------------------
Summary: JSON : selecting from an array of empty, null maps results in an exception
Key: DRILL-1660
URL: https://issues.apache.org/jira/browse/DRILL-1660
Project: Apache Drill
Issue Type: Bug
Components: Storage - JSON
Reporter: Rahul Challapalli
Assignee: Jason Altekruse
git.commit.id.abbrev=60aa446
I ran the below test against the branch from Jason's github fork which has some patches for bugs related to flatten which are not yet merged into the master.
Dataset used :
{code}
{
"id":1,
"evnts":[
{},
{"key":null}
]
}
{code}
The below query fails :
{code}
select id, evnts from `json_kvgenflatten/empty-null-map.json`;
+------------+------------+
| id | evnts |
+------------+------------+
