------------------------------------
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'.
