Jackey Lee created SPARK-29444: ---------------------------------- Summary: Add configuration to support JacksonGenrator to keep fields with null values Key: SPARK-29444 URL: https://issues.apache.org/jira/browse/SPARK-29444 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 3.0.0 Reporter: Jackey Lee
DataSet.toJSON will lost some column when field data is null. Maybe it is better to keep null data in some scenarios. Such as sparkmagic, which is widely used in jupyter with livy, we use toJSON to toJSON is used to get sql results. with toJSON sparkmagic may return empty results, which confused users. Maybe adding a config is the best choice. This configuration retains the current semantics and will remain fields with null until the configuration is modified. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
