title: ERROR Utils: Uncaught exception in thread SparkListenerBus
body: <p>I try to execute simple project with Apache Spark. This is my code SimpleApp.scala</p>
  
  <pre><code>/* SimpleApp.scala */
  import org.apache.spark.SparkContext
  import org.apache.spark.SparkContext._
  import org.apache.spark.SparkConf
  
  object SimpleApp {
    def main(args: Array[String]) {
      val logFile = "/home/hduser/spark-1.2.0-bin-hadoop2.4/README.md" // Should be some file on your system
      // val conf = new SparkConf().setAppName("Simple Application")
      val sc = new SparkContext("local", "Simple Job", "/home/hduser/spark-1.2.0-bin-hadoop2.4/")
      val logData = sc.textFile(logFile, 2).cache()
      val numAs = logData.filter(line =&gt; line.contains("hadoop")).count()
      val numBs = logData.filter(line =&gt; line.contains("see")).count()
      println("Lines with hadoop: %s, Lines with see: %s".format(numAs, numBs))
    }
  }
  </code></pre>
  
  <p>when I manually send this job to Spark with command line : <code>/home/hduser/spark-1.2.0-hadoop-2.4.0/bin/spark-submit --class "SimpleApp" --master local[4] target/scala-2.10/simple-project_2.10-1.0.jar</code> it's run successfully. </p>
  
  <p>if I run with <code>sbt run</code> and with the service apache spark is running, it's success, but in the end of log it give error like this : </p>
