> --------------------------------------
>
> Key: SPARK-25252
> URL: https://issues.apache.org/jira/browse/SPARK-25252
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.3.1
> Reporter: Maxim Gekk
> Assignee: Apache Spark
> Priority: Minor
>
> Need to improve the to_json function and make it more consistent with
> from_json by supporting arrays of any types (as root types). For now, it
> supports only arrays of structs and arrays of maps. After the changes the
> following code should work:
> {code:scala}
> select to_json(array('1','2','3'))
> > ["1","2","3"]
> select to_json(array(array(1,2,3),array(4)))
> > [[1,2,3],[4]]
> {code}
