ClassNotFoundException error when running the example code

[mrobot2]

I'm studying Spark. When I run the example, I encounter a exception. Can you help me to find the way to solve the error. I am using Spark 0.9.1. Thank you.

I got the same problem when I used TwitterUtils to create JavaDStream.
Below is part of my code.

            String[] filterString={...};
    ConfigurationBuilder cb = new ConfigurationBuilder();
    cb.setOAuthConsumerKey("...")
                .setOAuthConsumerSecret("...")
                .setOAuthAccessToken("...")
                .setOAuthAccessTokenSecret("...");
    Authorization oauth2 = new OAuth2Authorization(cb.build());
    JavaStreamingContext ssc = new JavaStreamingContext("spark://....", "Sample",
        new Duration(30000), System.getenv("SPARK_HOME"), JavaStreamingContext.jarOfClass(SimpleApp.class));
    JavaDStream<Status> tweets = TwitterUtils.createStream(ssc, oauth2, filterString);
