Re: Convert RDD to JSON Rdd and append more information

2016-09-20 Thread Deepak Sharma
Enrich the RDDs first with more information and then map it to some case
class , if you are using scala.
You can then use play api's
(play.api.libs.json.Writes/play.api.libs.json.Json) classes to convert the
mapped case class to json.

Thanks

Convert RDD to JSON Rdd and append more information

2016-09-20 Thread 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.

*{*
*TimeSeriesID : 1234*
*NumOfInputSamples : 1008 *
*Request Type : Fcast*
 16.9527493170273,20.1989561393151,15.7065424947394
 17.9527493170273,21.1989561393151,15.7065424947394
 18.9527493170273,22.1989561393151,15.7065424947394
}
