Subject basic twitter stream program not working.
Date Thu, 13 Nov 2014 09:28:25 GMT
Hi
       I am trying to run a basic twitter stream program but getting blank output. Please
correct me if I am missing something.

import org.apache.spark.SparkConf
import org.apache.spark.streaming.StreamingContext
import org.apache.spark.streaming.twitter.TwitterUtils
import org.apache.spark.streaming.Seconds
import org.apache.log4j.LogManager
import org.apache.log4j.Level

object Sparktwiter1 {
  def main(args: Array[String]) {
LogManager.getRootLogger().setLevel(Level.ERROR);
    System.setProperty("http.proxyHost", "proxy4.wipro.com");
    System.setProperty("http.proxyPort", "8080");
    System.setProperty("twitter4j.oauth.consumerKey", "")
    System.setProperty("twitter4j.oauth.consumerSecret", "")
    System.setProperty("twitter4j.oauth.accessToken", "")
    System.setProperty("twitter4j.oauth.accessTokenSecret", "")
    val sparkConf = new SparkConf().setAppName("TwitterPopularTags").setMaster("local").set("spark.eventLog.enabled",
"true")
    val ssc = new StreamingContext(sparkConf, Seconds(2))
    val stream = TwitterUtils.createStream(ssc, None)//, filters)
    stream.print
    val s1 = stream.flatMap(status => status.getText)
    s1.print
    val hashTags = stream.flatMap(status => status.getText.split(" ").filter(_.startsWith("#")))
    hashTags.print
     ssc.start()
    ssc.awaitTermination()
  }
}

Output
