[jira] [Updated] (SPARK-24651) Write null values when writing JSON

     [ https://issues.apache.org/jira/browse/SPARK-24651?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Matthew Liem updated SPARK-24651:
---------------------------------
    Description: 
Hello,

 Spark is configured to ignore the null values when writing JSON based off of JacksonMessageWriter - JsonInclude.Include.NON_NULL during serialization. 

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.
