ClassNotFound异常从apache Spark运行java程序时

Question

我有编译Java程序并尝试使用spark运行，但它显示ClassNotFound Exception，即使那里存在类文件。

    package org.apache.spark.examples;

    import org.apache.spark.SparkConf;
    import org.apache.spark.api.java.JavaRDD;
    import org.apache.spark.api.java.JavaSparkContext;
    import org.apache.spark.api.java.function;  

    public final class JavaHelloWorld
    {
         public static void main(String args[])throws Exception
         {

         SparkConf sparkConf = new SparkConf().setAppName("JavaSparkPi");
         JavaSparkContext jsc = new JavaSparkContext(sparkConf);
         System.out.println("Hello World... Niyat From Apache Spark");
         }
    }
