Hi Siva,
With below code, it is stuck up at
* sqlContext.read.json(rdd.map(_._2)).toDF()*
There are two partitions in topic.
I am running spark 1.6.2
val topics = "topic.name"
val brokers = "localhost:9092"
val topicsSet = topics.split(",").toSet
val sparkConf = new
SparkConf().setAppName("KafkaWeather").setMaster("local[5]")//spark://localhost:7077
val sc = new SparkContext(sparkConf)
val ssc = new StreamingContext(sc, Seconds(60))
val kafkaParams = Map[String, String]("metadata.broker.list" -> brokers, "
group.id" -> "xyz","auto.offset.reset"->"smallest")
val messages = KafkaUtils.createDirectStream[String, String, StringDecoder,
StringDecoder](ssc, kafkaParams, topicsSet)
messages.foreachRDD(rdd => {
if (rdd.isEmpty()) {
println("Failed to get data from Kafka. Please check that the Kafka
producer is streaming data.")
System.exit(-1)
}
val sqlContext =
org.apache.spark.sql.SQLContext.getOrCreate(rdd.sparkContext)
*val dataframe = sqlContext.read.json(rdd.map(_._2)).toDF()*
dataframe.foreach(println)
})
Below are logs,
