[sujeet jog]

Hi,

I have a Rdd of n rows,  i want to transform this to a Json RDD, and also
add some more information , any idea how to accomplish this .


ex : -

i have rdd with n rows with data like below ,  ,

 16.9527493170273,20.1989561393151,15.7065424947394
 17.9527493170273,21.1989561393151,15.7065424947394
 18.9527493170273,22.1989561393151,15.7065424947394


would like to add few rows highlited to the beginning of RDD like below, is
there a way to
do this and transform it to JSON,  the reason being i intend to push this
as input  to some application via pipeRDD for some processing, and want to
enforce a JSON structure on the input.

*{*
