--------------------------------------
Summary: Support IS_JSON
Key: SPARK-31106
URL: https://issues.apache.org/jira/browse/SPARK-31106
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 3.1.0
Reporter: Rakesh Raushan
Currently, null is returned when we come across invalid json. We should either
throw an exception for invalid json or false should be returned, like in other
DBMSs. Like in `json_array_length` function we need to return NULL for null
array. So this might confuse users.
DBMSs supporting this functions are :
* MySQL
* SQL Server
* Sqlite
* MariaDB
