如何在提供Scala .jar的Java中执行spark-submit？

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class SparkSubmitExample {
    public static void main(String[] args) {
        try {
            // 构建spark-submit命令
            String[] command = {
                    "spark-submit",
                    "--class",
                    "com.example.MySparkApp",
                    "--master",
                    "spark://localhost:7077",
                    "--deploy-mode",
                    "client",
                    "--executor-memory",
                    "2g",
                    "/path/to/your/app.jar"
            };

            // 创建进程并执行命令
            ProcessBuilder processBuilder = new ProcessBuilder(command);
            Process process = processBuilder.start();

            // 读取进程输出
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }

            // 等待进程执行完成
            int exitCode = process.waitFor();
            System.out.println("Exit code: " + exitCode);
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
