Hi All,
My application works when I use the spark-submit with master=local[*].
But if I deploy the application to a standalone cluster
master=spark://master:7077 then the application polls twice twice from
kafka topic and then it stops working. I don't get any error logs.
I can see application connecting to kafka but it just doesn't seem to
receive any messages in a cluster standalone environment.
The application code is as followed:
val sc = new SparkContext(sparkConf)
val sqlContext = new SQLContext(sc)
import sqlContext._
val ssc = new StreamingContext(sparkConf, Seconds(3))
ssc.checkpoint("checkpoint")
val dStream = KafkaUtils.createStream(ssc, zkQuorum, group, topicpMap)
val eventData =
dStream.map(_._2).window(Seconds(9)).map(_.split(",")).map(data =>
Data(data(0), data(1), data(2), data(3), data(4)))
val result = eventData.transform((rdd, time)=>{
sqlContext.registerRDDAsTable(rdd, "data")
sql("SELECT count(state) FROM data WHERE state='Active'")
})
result.print()
ssc.start()
ssc.awaitTermination()
I would appreciate your help.
Thanks,
Ali
