Hi,
I’m trying to submit a streaming application on my standalone Spark cluster,
this is my code:
import akka.actor.{Props, ActorSystem, Actor}
import akka.http.scaladsl.Http
import akka.http.scaladsl.model.HttpRequest
import akka.http.scaladsl.model.Uri
import akka.stream.ActorMaterializer
import org.apache.spark.streaming.{Seconds, StreamingContext}
import org.apache.spark.streaming.receiver.ActorHelper
import org.apache.spark.{SparkEnv, SparkContext, SparkConf}
object Boot extends App {
val driverPort = 7777
val conf = new SparkConf().
setAppName("TestSpark").
set("spark.driver.port", driverPort.toString).
set("spark.driver.host", "localhost").
setMaster("spark://<master-uri>:7077").
set("spark.akka.logLifecycleEvents", "true")
val sc = new SparkContext(conf)
val ssc = new StreamingContext(sc, Seconds(1))
val meetup = ssc.actorStream[String](Props[CustomReceiver], "attore")
ChunkReceiver.start(driverPort, "localhost", "attore")
meetup.print
ssc.start
}
object ChunkReceiver {
def start(driverPort:Int, driverHost:String, actorName:String) {
Thread.sleep(5000)
implicit val system = ActorSystem("client")
import system.dispatcher
implicit val materializer = ActorMaterializer()
val url =
s"akka.tcp://sparkDriver@$driverHost:$driverPort/user/Supervisor0/$actorName"
val actor = SparkEnv.get.actorSystem.actorSelection(url)
val source = Uri("http://stream.meetup.com/2/rsvps";)
Http().
singleRequest(HttpRequest(uri = source)).
flatMap { response =>
response.entity.dataBytes.runForeach { chunk =>
actor ! chunk.utf8String
}
}
}
}
class CustomReceiver extends Actor with ActorHelper {
log.info("Starting receiver ...")
override def receive = {
case s:String => store(s)
}
}
And these are the messages generate by Spark:

the application doesn’t terminate with errors, but the CustomReceiver
doesn’t receive any data.
Thank you very much for the help,
