Please let me know if the previous status, `Resolution = Won't Fix` and `Fix
Version = 3.0.0`, was correct.
> Prevent null rows from JSON parser
> ----------------------------------
>
> Key: SPARK-25935
> URL: https://issues.apache.org/jira/browse/SPARK-25935
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: Max Gekk
> Priority: Minor
>
> Currently, JSON parser can produce nulls if it cannot detect any valid JSON
> token on the root level, see
> https://github.com/apache/spark/blob/4d6704db4d490bd1830ed3c757525f41058523e0/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/json/JacksonParser.scala#L402
> . As a consequence of that, the from_json() function can produce null in the
> PERMISSIVE mode. To prevent that, need to throw an exception which should
> treat as a bad record and handled according specified mode.
