Hi,
I am beginner in Spark , this is sample data I get from Kafka stream:
{"id":
"9f5ccb3d5f4f421392fb98978a6b368f","coordinate":{"ax":"1.20","ay":"3.80","az":"9.90","oa":"8.03","ob":"8.8","og":"9.97"}}
val lines = KafkaUtils.createStream(ssc, zkQuorum, group, topicMap).map(_._2)
val jsonf =
lines.map(JSON.parseFull(_)).map(_.get.asInstanceOf[scala.collection.immutable.Map[String,
Any]])
I am getting a, DSTream[Map[String,Any]]. I need to store each coordinate
values in the below Cassandra schema
CREATE TABLE iotdata.coordinate (
id text PRIMARY KEY, ax double, ay double, az double, oa double, ob double,
oz double
)
For this what transformations I need to apply before I execute
saveToCassandra().
Thank You,
Prateek
