我想连接到apachespark，它是从本地机器上运行的spring启动应用程序在远程服务器上设置的。我在网上看到了一些示例，但都在本地系统上配置了spark，并在spark.home中提供了可安装的路径。
我想要一个类似的设置，但不是Spark.home指向本地系统，它应该连接到一个远程机器。任何帮助都将不胜感激。
下面是代码

import org.apache.spark.SparkConf;
import org.apache.spark.api.java.JavaSparkContext;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

@SpringBootApplication

public class SpringSparkApplication {

    @Value("${spark.app.name}")
    private String appName;
    @Value("${spark.master}")
    private String masterUri;

    @Bean
    public SparkConf conf() {
        return new SparkConf().setAppName(appName).setMaster(masterUri);
    }

    @Bean
    public JavaSparkContext sc() {
        return new JavaSparkContext(conf());
    }

    public static void main(String[] args) {
        SpringApplication.run(SpringSparkApplication.class, args);
    }

}

这些属性是：
spark.app.name=ayush spark.master=spark://192.x.x.50:7077
