Submit Spark Task

I installed a spark on ubuntu 14.04 after this tutorial http://blog.prabeeshk.com/blog/2014/10/31/install-apache-spark-on-ubuntu-14-dot-04/

I can run the examples presented inside the spark and it seems to work.

The problem is that I cannot create a scala file and execute it with a spark. This is what I did as recommended by https://spark.apache.org/docs/latest/quick-start.html

My standalone application:

/* SimpleApp.scala */
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf
import org.apache.commons.math3.random.RandomDataGenerator


object SimpleApp {
  def main(args: Array[String]) {
    val logFile = "/home/donbeo/Applications/spark/spark-1.1.0/README.md" // Should be some file on your system
    val conf = new SparkConf().setAppName("Simple Application")
    val sc = new SparkContext(conf)
    val logData = sc.textFile(logFile, 2).cache()
    val numAs = logData.filter(line => line.contains("a")).count()
    val numBs = logData.filter(line => line.contains("b")).count()
    println("Lines with a: %s, Lines with b: %s".format(numAs, numBs))


    println("A random number")

  val randomData = new RandomDataGenerator()

  println(randomData.nextLong(0, 100))
  }
}

and my sbt file:

   name := "Simple Project"

version := "1.0"

scalaVersion := "2.10.4"

libraryDependencies += "org.apache.spark" %% "spark-core" % "1.1.0"

libraryDependencies += "org.apache.commons" % "commons-math3" % "3.3"

my project structure:

donbeo@donbeo-HP-EliteBook-Folio-9470m:~/Documents/scala_code/simpleApp$ find .
.
./src
./src/main
./src/main/scala
./src/main/scala/SimpleApp.scala~
./src/main/scala/SimpleApp.scala
./simple.sbt
donbeo@donbeo-HP-EliteBook-Folio-9470m:~/Documents/scala_code/simpleApp$

and then I ran

donbeo@donbeo-HP-EliteBook-Folio-9470m:~/Documents/scala_code/simpleApp$ sbt package

donbeo@donbeo-HP-EliteBook-Folio-9470m:~/Documents/scala_code/simpleApp$

and in the last step I get an error

Am I doing something wrong? How can i decide?
