Tongwei created SPARK-56659:
-------------------------------
Summary: Show function resources in DESCRIBE FUNCTION output
Key: SPARK-56659
URL: https://issues.apache.org/jira/browse/SPARK-56659
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.5.1
Reporter: Tongwei
When a persistent function is created with `USING JAR/FILE` resources,
`DESCRIBE FUNCTION` does not display those resources in its output.
For example:
```sql
CREATE FUNCTION my_udf AS 'com.example.MyUDF' USING JAR
'hdfs:///path/to/my-udf.jar';
DESCRIBE FUNCTION my_udf;
Current output:
Function: spark_catalog.default.my_udf
Class: com.example.MyUDF
Usage: N/A
Expected output:
Function: spark_catalog.default.my_udf
Class: com.example.MyUDF
Usage: N/A
Resource: jar hdfs:///path/to/my-udf.jar
