Zeppelin: java.lang.NoClassDefFoundError: org/apache/spark/Logging

Question

I'm trying to find trending hashtags on twitter using Spark streaming.

os -> mac os

spark-version -> 2.2.1

scala-version -> 2.11.8

zeppelin-version -> 0.7.3

Above tools and versions I'm using. I have added three different jars to my zeppelin notebook:

twitter4j-core-4.0.4.jar

twitter4j-stream-4.0.4.jar

spark-streaming-twitter_2.10-1.0.0.jar

import org.apache.spark._
import org.apache.spark.SparkContext._
import org.apache.spark.streaming._
import org.apache.spark.streaming.twitter._
import org.apache.spark.streaming.StreamingContext._

def setUpTwitter() = {
    import scala.io.Source
    for (line <- Source.fromFile("/Users/abhijeet/Documents/sparkscala/SparkScala/twitter.txt").getLines) {
        val fields = line.split(" ")
        if (fields.length == 2){
            System.setProperty("twitter4j.oauth." + fields(0), fields(1))
        }
    }
}
setUpTwitter()
val ssc = new StreamingContext(sc, Seconds(1))
def setupLogging() = {
    import org.apache.log4j.{Level, Logger}
    val rootLogger = Logger.getRootLogger()
    rootLogger.setLevel(Level.ERROR)
}
setupLogging()

Upto this point in code zeppelin worked fine

val tweets = TwitterUtils.createStream(ssc, None)

In above line it started throwing error

After that I found org.apache.spark.Logging is available in Spark version 1.5.2 or lower version. It is not in the 2.0.0.

My concern is I'm using Zeppelin. I have no pom file here or anything to change the version.

What is the way to resolve this error?

Any help would be greatly appreciated!

Thank you

I found the solution by adding the jar

spark-core_2.11-1.5.2.logging.jar
