hvanhovell opened a new pull request #23397: [SPARK-26495][SQL] Simplify the SelectedField extractor. URL: https://github.com/apache/spark/pull/23397 ## What changes were proposed in this pull request? The current `SelectedField` extractor is somewhat complicated and it seems to be handling cases that should be handled automatically: - `GetArrayItem(child: GetStructFieldObject())` - `GetArrayStructFields(child: GetArrayStructFields())` - `GetMap(value: GetStructFieldObject())` This PR removes those cases and simplifies the extractor by passing down the data type instead of a field. ## How was this patch tested? Existing tests.
