> Key: HIVE-8846
> URL: https://issues.apache.org/jira/browse/HIVE-8846
> Project: Hive
> Issue Type: Bug
> Components: File Formats
> Affects Versions: 0.11.0, 0.12.0, 0.13.0, 0.13.1
> Reporter: Gregory Hart
> Priority: Critical
> Labels: orcfile
>
> The OrcListObjectInspector and OrcMapObjectInspector classes do not check for
> null data and instead throw an exception. To comply with the JavaDocs for
> ListObjectInspector and MapObjectInspector, these classes should be updated
> to check for null data.
> The following checks should be added for OrcListObjectInspector:
> - getListElement(Object, int) should return null for null list,
> out-of-the-range index
> - getListLength(Object) should return -1 for data = null
> - getList(Object) should return null for data = null
> The following checks should be added for OrcMapObjectInspector:
> - getMap(Object) should return null for data = null
> - getMapSize(Object) return -1 for NULL map
