Hi all,
I'm try to write a spark stream programme so i read the spark online document
,according the document i write the programe like this :
import org.apache.spark.SparkConf
import org.apache.spark.streaming._
import org.apache.spark.streaming.StreamingContext._
object SparkStreamTest {
def main(args: Array[String]) {
val conf = new SparkConf()
val ssc = new StreamingContext(conf, Seconds(1))
val lines = ssc.socketTextStream(args(0), args(1).toInt)
val words = lines.flatMap(_.split(" "))
val pairs = words.map(word => (word, 1))
val wordCounts = pairs.reduceByKey(_ + _)
wordCounts.print()
ssc.start() // Start the computation
ssc.awaitTermination() // Wait for the computation to terminate
}
}
for test i first start listen a port by this:
nc -lk 9999
and then i submit job by
spark-submit --master local[2] --class com.nd.hxf.SparkStreamTest
spark-test-tream-1.0-SNAPSHOT-job.jar localhost 9999
everything is okay
but when i run it on yarn by this :
spark-submit --master yarn-client --class com.nd.hxf.SparkStreamTest
spark-test-tream-1.0-SNAPSHOT-job.jar localhost 9999
it wait for a longtime and repeat output somemessage a apart of the output is
like this:
