>
> 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
> Priority: Major

> It seems that wildcards (star) 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'.
