Michael Armbrust updated SPARK-17764:
-------------------------------------
Target Version/s: 2.1.0
> to_json function for parsing Structs to json Strings
> ----------------------------------------------------
>
> Key: SPARK-17764
> URL: https://issues.apache.org/jira/browse/SPARK-17764
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Hyukjin Kwon
>
> After SPARK-17699, now Spark supprots {{from_json}}. It might be nicer if we
> have {{to_json}} too, in particular, in the case to write out dataframes by
> some data sources not supporting nested structured types.
