How to convert String data to RDD.

[RP]

Hello Guys,
 Spark noob here. I am trying to create RDD from  JSON data  fetched 
from URL parsing.
My URL parsing function gives me JSON in string format.
How do I convert JSON string to JSONRDD so that I can use it in SparkSQL.


// get json data in string fromat
val jsonURLData = getUrlAsString("https://somehost.com/test.json";)

val jsonDataRDD = ?

val  json1  =  sqlContext.jsonRDD(jsonDataRDD)

Thanks,
RP
