> Key: SPARK-24651
> URL: https://issues.apache.org/jira/browse/SPARK-24651
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 2.3.1
> Reporter: Matthew Liem
> Priority: Minor
>
> Hello,
> Spark is configured to ignore the null values when writing JSON based off of
> JacksonMessageWriter.scala during serialization:
> |mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL)|
> In some scenarios it is useful to maintain these fields..looking to see if
> this functionality can be added or configurable to set e.g. use
> Include.ALWAYS or other properties depending on requirement.
