Hi Kant, You can check the getValuesMap <https://spark.apache.org/docs/2.2.0/api/java/org/apache/spark/sql/Row.html#getValuesMap-scala.collection.Seq->. I found this post <https://stackoverflow.com/a/41602178/8356352> useful, it is in Scala but should be a good starting point. An alternative approach is combine the 'struct' and 'to_json' functions <https://spark.apache.org/docs/2.2.0/api/java/org/apache/spark/sql/functions.html>. I have not tested this in Java but I am using it in Python.
