> 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
> Priority: Major
> 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'.
