我用spark实现了一个简单的java并行算法。但我不知道如何在googledataproc集群上运行它。我在网上找到了很多使用python或scala的资源，但对java来说还不够。这是密码

public class Prime {

    List<Integer> primes = new ArrayList<>();

    //Method to calculate and count the prime numbers
    public void countPrime(int n){
        for (int i = 2; i < n; i++){
            boolean  isPrime = true;

            //check if the number is prime or not
            for (int j = 2; j < i; j++){
                if (i % j == 0){
                    isPrime = false;
                    break;  // exit the inner for loop
                }
            }

            //add the primes into the List
            if (isPrime){
                primes.add(i);
            }
        }
    }

    //Main method to run the program
    public static void main(String[]args){
        //creating javaSparkContext object
        SparkConf conf = new SparkConf().setAppName("haha").setMaster("local");
        JavaSparkContext sc = new JavaSparkContext(conf);
        //new prime object
        Prime prime = new Prime();
        prime.countPrime(100000);

        //parallelize the collection
        JavaRDD<Integer> rdd = sc.parallelize(prime.primes , 4);
        long count = rdd.filter(e  -> e == 2|| e % 2 != 0).count(); 
    }
}
