Spark Scala NoClassDefFoundError: org/apache/spark/Logging

Question

I've checked a bunch of other forums and posts, but I can't seem to narrow down the issue. All I keep seeing is people saying not to use logging and how it's deprecated, but I don't even know where I'm using it in my code.

When I run the following code:

import org.apache.spark._
import org.apache.spark.streaming._
import org.apache.spark.streaming.twitter._
import twitter4j.Status

object TrendingHashTags {
  def main(args: Array[String]): Unit = {
    if (args.length < 8) {
      System.err.println("Usage: TrendingHashTags <consumer key> <consumer secret> " +
                          "<access token> <access token secret> " +
                          "<language> <batch interval> <min-threshold> <show-count> " +
                          "[<filters>]")
      System.exit(1)
    }

    val Array(consumerKey, consumerSecret, accessToken, accessTokenSecret,
                              lang, batchInterval, minThreshold, showCount ) = args.take(8)
    val filters = args.takeRight(args.length - 8)

    System.setProperty("twitter4j.oauth.consumerKey", consumerKey)
    System.setProperty("twitter4j.oauth.consumerSecret", consumerSecret)
    System.setProperty("twitter4j.oauth.accessToken", accessToken)
    System.setProperty("twitter4j.oauth.accessTokenSecret", accessTokenSecret)

    val conf = new SparkConf().setMaster(("local[4]")).setAppName("TrendingHashTags")
    val ssc = new StreamingContext(conf, Seconds(batchInterval.toInt))
    ssc.checkpoint("checkpoint")
    val tweets = TwitterUtils.createStream(ssc, None, filters)
    val tweetsFilteredByLang = tweets.filter{tweet => tweet.getLang() == lang}
    val statuses = tweetsFilteredByLang.map{tweet => tweet.getText()}
    val words = statuses.flatMap{status => status.split("""\s+""")}
    val hashTags = words.filter{word => word.startsWith("#")}
    val hashTagPairs = hashTags.map{hashtag => (hashtag, 1)}
    val tagsWithCounts = hashTagPairs.updateStateByKey(
      (counts: Seq[Int], prevCount: Option[Int]) =>
        prevCount.map{c => c + counts.sum}.orElse{Some(counts.sum)}
    )
    val topHashTags = tagsWithCounts.filter { case (t, c) =>
      c > minThreshold.toInt
    }
    val sortedTopHashTags = topHashTags.transform{rdd =>
      rdd.sortBy({case(w, c) => c}, false)
    }
    sortedTopHashTags.print(showCount.toInt)
    ssc.start()
    ssc.awaitTermination()
  }
}

I get the following error stack trace:

Here are my build.sbt contents:

name := "sparkStreaming"

version := "0.1"

scalaVersion := "2.11.12"

libraryDependencies ++= Seq("org.apache.spark" %% "spark-core" % "2.4.5",
  "org.apache.spark" %% "spark-sql" % "2.4.5",
  "org.apache.spark" %% "spark-streaming" % "2.4.5" % "provided",
  "org.apache.spark" %% "spark-streaming-twitter" % "1.6.3")

Does this answer your question? [Spark Twitter Streaming exception : (org.apache.spark.Logging) classnotfound](https://stackoverflow.com/questions/38893655/spark-twitter-streaming-exception-org-apache-spark-logging-classnotfound) — Duelist, May 07 '20 at 21:50

Clear indication is, some where internally you are using lower version of spark... (spark 1.5 may be)

sbt inspect tree clean

you can check with this. for maven users mvn depdency:tree will give all the dependencies used list

One more thing is you are using

  "org.apache.spark" %% "spark-streaming" % "2.4.5" % "provided",

change it to default maven scope compile and see.
