Try running it in local mode. Looks like a jar conflict/missing.
SparkConf conf = new SparkConf().setAppName("JavaWordCount");
conf.set("spark.io.compression.codec","org.apache.spark.io.LZ4CompressionCodec");
conf.setMaster("*local[2]*").setSparkHome(System.getenv("SPARK_HOME"));
JavaSparkContext jsc = new JavaSparkContext(conf);
jsc.addJar(“myJar.jar”);
new JavaWordCount(jsc).doJob();
Thanks
Best Regards
