> Support single quotes json parsing for get_json_object and json_tuple
> ---------------------------------------------------------------------
>
> Key: SPARK-30330
> URL: https://issues.apache.org/jira/browse/SPARK-30330
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.3, 2.4.4
> Reporter: Fang Wen
> Priority: Major
> Labels: release-notes
>
> I execute some query as
> {code:java}
> select get_json_object(ytag, '$.y1') AS y1 from t4{code}
> SparkSQL return null but Hive return correct results.
> In my production environment, ytag is a json wrapped by single quotes,as follows
> {code:java}
> {'y1': 'shuma', 'y2': 'shuma:shouji'}
> {'y1': 'jiaoyu', 'y2': 'jiaoyu:gaokao'}
> {'y1': 'yule', 'y2': 'yule:mingxing'}
> {code}
> Then l realized some functions including get_json_object and json_tuple does not support single quotes json parsing. It will return null for this situation.
> I think such a treatment is unfriendly for users.
