问题
I am trying to stream data using spark-streaming-kafka-0-10_2.11 artifact and 2.1.1 version along with spark-streaming_2.11 version 2.1.1 and kafka_2.11(0.10.2.1 version).
When I start the program, Spark is not streaming data and neither it is throwing any error.
Below is my code, dependencies, and response.
Dependencies:
"org.apache.kafka" % "kafka_2.11" % "0.10.2.1",
"org.apache.spark" % "spark-streaming-kafka-0-10_2.11" % "2.1.1",
"org.apache.spark" % "spark-streaming_2.11" % "2.1.1"
Code:
val sparkConf = new SparkConf().setMaster("local[*]").setAppName("kafka-dstream").set("spark.driver.allowMultipleContexts", "true")
val sc = new SparkContext(sparkConf)
val ssc = new StreamingContext(sc, Seconds(5))
val kafkaParams = Map[String, Object](
"bootstrap.servers" -> "ec2-xx-yy-zz-abc.us-west-2.compute.amazonaws.com:9092",
"key.deserializer" -> classOf[StringDeserializer],
"value.deserializer" -> classOf[StringDeserializer],
"group.id" -> ("java-test-consumer-" + random.nextInt()+"-" +
System.currentTimeMillis()),
"auto.offset.reset" -> "latest",
"enable.auto.commit" -> (false: java.lang.Boolean)
)
val topics = Array("test")
val stream = KafkaUtils.createDirectStream[String, String](
ssc,
PreferConsistent,
Subscribe[String, String](topics, kafkaParams)
)
stream.foreachRDD(f=>f.foreachPartition(f=>f ->{
while (f.hasNext) {
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>"+f.next().key());
}
}))
ssc.start()
ssc.awaitTermination()

The code starts waiting here,neither it throws error,nor streams.
And what else i observed is,if i don't use "org.apache.kafka" % "kafka_2.11" % "0.10.2.1" dependency, am getting
"Exception in thread "main" org.apache.kafka.common.protocol.types.SchemaException: Error reading field 'topic_metadata': Error reading array of size 291941, only 32 bytes available" error,
so i used kafka_2.11(0.10.2.1 version) dependency.
