[jira] [Created] (DRILL-5965) Array index access returns an empty
array
Khurram Faraaz created DRILL-5965:
-------------------------------------
Summary: Array index access returns an empty array
Key: DRILL-5965
URL: https://issues.apache.org/jira/browse/DRILL-5965
Project: Apache Drill
Issue Type: Bug
Components: Storage - JSON
Affects Versions: 1.12.0
Reporter: Khurram Faraaz
Accessing an array with [<array-index>] from JSON data, returns an empty string, whereas it should return the actual data from the array at the index and not an empty array.
Drill 1.11.0-mapr commit: 065d72ba48c7af6b389b763753ecb6bf7d229ce8
