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
