SparkLauncher提交spark任务到spark3.x集群，指定jar包路径在minio上java怎么实现

可以使用Java的Minio SDK来实现将Jar包上传到Minio上，然后使用SparkLauncher提交任务时指定Jar包的Minio路径。

以下是一个示例代码：

import io.minio.MinioClient;
import io.minio.errors.MinioException;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

public class MinioUploader {
    private static final String MINIO_ENDPOINT = "http://minio.example.com";
    private static final String MINIO_ACCESS_KEY = "accessKey";
    private static final String MINIO_SECRET_KEY = "secretKey";
    private static final String MINIO_BUCKET_NAME = "spark-jars";

    public static void uploadJar(String localPath, String remotePath) throws IOException, MinioException {
        // Create a MinioClient object
        MinioClient minioClient = new MinioClient(MINIO_ENDPOINT, MINIO_ACCESS_KEY, MINIO_SECRET_KEY);

        // Create the bucket if it doesn't exist
        if (!minioClient.bucketExists(MINIO_BUCKET_NAME)) {
            minioClient.makeBucket(MINIO_BUCKET_NAME);
        }

        // Read the jar file into a byte array
        Path path = Paths.get(localPath);
        byte[] data = Files.readAllBytes(path);

        // Upload the jar file to Minio
        minioClient.putObject(MINIO_BUCKET_NAME, remotePath, data, "application/java-archive");
    }
}

然后在SparkLauncher提交任务时，指定Jar包的Minio路径，例如：

import org.apache.spark.launcher.SparkLauncher;

public class SparkJobLauncher {
    private static final String APP_NAME = "MySparkApp";
    private static final String MASTER = "spark://spark-master.example.com:7077";
    private static final String MAIN_CLASS = "com.example.MySparkJob";
    private static final String MINIO_ENDPOINT = "http://minio.example.com";
    private static final String MINIO_ACCESS_KEY = "accessKey";
    private static final String MINIO_SECRET_KEY = "secretKey";
    private static final String MINIO_BUCKET_NAME = "spark-jars";
    private static final String JAR_REMOTE_PATH = "my-spark-job.jar";

    public static void main(String[] args) throws Exception {
        // Upload the jar to Minio
        MinioUploader.uploadJar("my-spark-job.jar", JAR_REMOTE_PATH);

        // Create a SparkLauncher object
        SparkLauncher launcher = new SparkLauncher()
                .setAppName(APP_NAME)
                .setMaster(MASTER)
                .setMainClass(MAIN_CLASS)
                .setAppResource(MINIO_ENDPOINT + "/" + MINIO_BUCKET_NAME + "/" + JAR_REMOTE_PATH)
                .addAppArgs("arg1", "arg2");

        // Submit the job
        Process process = launcher.launch();
        process.waitFor();
    }
}

在上面的代码中，`setAppResource`方法指定了Jar包的Minio路径，`addAppArgs`方法指定了任务的参数。可以根据实际情况进行调整。
