teenagers .toJSON gives the json but it does not preserve the parent ids
meaning if the input was {"name":"Yin",
"address":{"city":"Columbus","state":"Ohio"},"age":20}
val x= sqlContext.sql("SELECT name, address.city, address.state ,age FROM
people where age>19 and age <=30 ").toJSON
x.collect().foreach(println)
This returns back , missing address.
{"name":"Yin","city":"Columbus","state":"Ohio","age":20}
Is this a bug ?
