------------------------------------

             Summary: Wildcards not working in get_json_object
                 Key: SPARK-32789
                 URL: https://issues.apache.org/jira/browse/SPARK-32789
             Project: Spark
          Issue Type: Bug
          Components: PySpark
    Affects Versions: 2.4.4
            Reporter: Thomas Uhren
         Attachments: image-2020-09-03-13-22-38-569.png

It seems that wildcards (*) are not supported when using {{get_json_object}}:
{code:java}
spark.sql("""select get_json_object('{"k":{"value":"abc"}}', '$.*.value') as j""").show()
{code}
This results in {{null}} while it should return 'abc'. It works if I replace * with 'k'.
