Spark Streaming - java.lang.NoSuchMethodError错误

Question

I am trying to access the streaming tweets from Spark Streaming.

This is the software configuration.

Ubuntu 14.04.2 LTS

scala -version

Scala code runner version 2.11.7 -- Copyright 2002-2013, LAMP/EPFL

spark-submit --version

Spark version 1.6.0

Following is the code.

object PrintTweets
{
 def main(args: Array[String]) {

  // Configure Twitter credentials using twitter.txt
  setupTwitter()

  // Set up a Spark streaming context named "PrintTweets" that runs locally using
  // all CPU cores and one-second batches of data
  val ssc = new StreamingContext("local[*]", "PrintTweets", Seconds(1))

  // Get rid of log spam (should be called after the context is set up)
  setupLogging()

  // Create a DStream from Twitter using our streaming context
  val tweets = TwitterUtils.createStream(ssc, None)


  // Now extract the text of each status update into RDD's using map()
  val statuses = tweets.map(status => status.getText())

  // Print out the first ten
  statuses.print()

  // Kick it all off
  ssc.start()
  ssc.awaitTermination()
 }
}

Utilities.scala

object Utilities {
/** Makes sure only ERROR messages get logged to avoid log spam. */
def setupLogging() = {
  import org.apache.log4j.{Level, Logger}   
  val rootLogger = Logger.getRootLogger()
  rootLogger.setLevel(Level.ERROR)   
}

/** Configures Twitter service credentials using twiter.txt in the   main workspace directory */
def setupTwitter() = {
  import scala.io.Source

  for (line <- Source.fromFile("./data/twitter.txt").getLines) {
   val fields = line.split(" ")
   if (fields.length == 2) {
    System.setProperty("twitter4j.oauth." + fields(0), fields(1))
   }
 }

}

}

Issues:

Since it needs the twitter4j library, i have added
twitter4j-core-4.0.4, twitter4j-stream-4.0.4 in eclipse build path as external jars.

Then i ran the program, it didnt throw any error. But the tweets not appearing in console. It were empty.

So i see some forums and downgraded twitter4j to 3.0.3. Also in Eclipse i chosen Scala 2.10 Library container in Build Path window.

After that i got java.lang.NoSuchMethodError run-time error.

16/05/14 11:46:01 ERROR Executor: Exception in task 0.0 in stage 0.0 (TID 0)

Please help me to resolve this. Initially i have installed spark by built using Scala 2.11. Is that the problem. Do i need uninstall everything and re-install Scala 2.10, then Spark pre-compiled package.

Or apart from Scala 2.11, do i need to have Scala 2.10 in my system?

Answer 1

The above exception seems to be caused by the incompatibility of spark version 1.6.0 and twitter4j 3.0.3 version .

twitter4j.TwitterStream which is being passed in the onStart method of org.apache.spark.streaming.twitter.TwitterReceiver , has method addListener which takes instance of twitter4j.StreamListener .

twitter4j 3.0.3 version has no method twitter4j.TwitterStream.addListener(StreamListener) , instead it has few other addListener methods, which take the subclass of StreamListener .

twitter4j 4.0.4 version has the desired method, so that's why no error comes with this library. So changing to twitter4j 3.0.3 version will not solve the problem.

Problem is somewhere else.

In my case. I had spark java project. I cleaned pom file and start adding in order. First resolved spark related errors, then spark launcher, next on ward based on bigger library. Note I was using cdh6.2.0 environment
