Hi,
I have a DStream which is a stream of RDD[String].
How can I pass a DStream to sqlContext.jsonRDD and work with it as a DF ?
Thank you.

Something like:
dstream.foreachRDD { rdd =>
val df = sqlContext.read.json(rdd)
df.select(…)
}
https://spark.apache.org/docs/latest/streaming-programming-guide.html#output-operati
ork it as if it were a standard RDD dataset.
