             Summary: from_json function for parsing json Strings into Structs
                 Key: SPARK-17699
                 URL: https://issues.apache.org/jira/browse/SPARK-17699
             Project: Spark
          Issue Type: New Feature

            Reporter: Michael Armbrust
            Assignee: Michael Armbrust
            Priority: Critical


Today, we have good support for reading standalone JSON data.  However, sometimes (especially when reading from streaming sources such as Kafka) the JSON is embedded in an envelope that has other information we'd like to preserve.  It would be nice if we could also parse JSON string columns, while preserving the original JSON schema.
