title: Spark-Submit Error: Cannot load main class from JAR file
body: <p>I am trying to <code>spark-submit</code> an application in Scala cluster mode.It was working fine in PySpark but while trying to run with Scala the above error is popping up. If I have to add SBT and Maven dependencies can you elaborate the procedure(I am not able to find in Google)</p>
  
  <p>This is my code:</p>
  
  <pre><code>import org.apache.spark.SparkContext
  import org.apache.spark.SparkContext._
  import org.apache.spark.SparkConf
  
  object MyFirst {
    def main(args: Array[String]) {
      // create Spark context with Spark configuration
      val sc = new SparkContext(new SparkConf().setAppName("Spark Count"))
  
      // get threshold
      val threshold = args(1).toInt
  
      // read in text file and split each document into words
      val tokenized = sc.textFile(args(0)).flatMap(_.split(" "))
  
      // count the occurrence of each word
      val wordCounts = tokenized.map((_, 1)).reduceByKey(_ + _)
  
      // filter out words with fewer than threshold occurrences
      val filtered = wordCounts.filter(_._2 &gt;= threshold)
  
      // count characters
      val charCounts = filtered.flatMap(_._1.toCharArray).map((_, 1)).reduceByKey(_ + _)
  
      System.out.println(charCounts.collect().mkString(", "))
    }
  }
  </code></pre>
  
  <p>Here is my Build.sbt </p>
  
  <pre><code>name := "MyFirst"
  
  scalaVersion := "2.10.3"
  
  // https://mvnrepository.com/artifact/org.apache.spark/spark-core
  libraryDependencies += "org.apache.spark" %% "spark-core" % "2.2.0"
  </code></pre>
