Thread(new Runnable() {
@Override
public void run() {
SparkConf conf = new SparkConf();
conf.setAppName("SparkDemo");

JavaRDD<String> array =
sparkContext.parallelize(Lists.newArrayList("1", "2", "3", "4"));
System.out.println(array.count());
}
}), 0, 5000, TimeUnit.MILLISECONDS);

main method was finished, but sub thread may be not finished.
so should not invoke finish to shutdown dirver thread.
