> Key: SPARK-8440
> URL: https://issues.apache.org/jira/browse/SPARK-8440

> Components: Streaming

> Reporter: Bartek

> hi,
> I'm trying to run simple kafka spark streaming example over spark-shell:
> {code}
> sc.stop
> import org.apache.spark.SparkConf
> import org.apache.spark.SparkContext._
> import kafka.serializer.DefaultDecoder
> import org.apache.spark.streaming._
> import org.apache.spark.streaming.kafka._
> import org.apache.spark.storage.StorageLevel
> val sparkConf = new SparkConf().setAppName("Summarizer").setMaster("local")
> val ssc = new StreamingContext(sparkConf, Seconds(10))
> val kafkaParams = Map[String, String]("zookeeper.connect" ->
> "127.0.0.1:2181", "group.id" -> "test")
> val messages = KafkaUtils.createStream[Array[Byte], Array[Byte],
> DefaultDecoder, DefaultDecoder](ssc, kafkaParams, Map("test" -> 1),
> StorageLevel.MEMORY_ONLY_SER).map(_._2)
> messages.foreachRDD { pairRDD =>
> println(s"DataListener.listen() [pairRDD = ${pairRDD}]")
> println(s"DataListener.listen() [pairRDD.count = ${pairRDD.count()}]")
> pairRDD.foreach(row => println(s"DataListener.listen() [row = ${row}]"))
> }
> ssc.start()
> ssc.awaitTermination()
> {code}
> in spark output i'm able to find log {{println(s"DataListener.listen()
> [pairRDD = ${pairRDD}]")}} but can't find output of
> {{println(s"DataListener.listen() [pairRDD.count = ${pairRDD.count()}]")}}
> and {{println(s"DataListener.listen() [row = ${row}]")}}
> it's my spark-shell full output - http://pastebin.com/sfxbYYga
> any ideas what i'm doing wrong? thanks!
