如何将唯一的整数键分配给Apache Spark Java应用程序中的每个Apache Spark Executor？

import org.apache.spark.api.java.JavaSparkContext;
import org.apache.spark.api.java.function.FlatMapFunction;
import org.apache.spark.broadcast.Broadcast;
import org.apache.spark.sql.SparkSession;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.UUID;

public class SparkApp {
    public static void main(String[] args) {
        SparkSession spark = SparkSession.builder()
                .appName("SparkApp")
                .master("local[*]")
                .getOrCreate();

        JavaSparkContext jsc = new JavaSparkContext(spark.sparkContext());

        // 生成唯一的UUID
        UUID uuid = UUID.randomUUID();

        // 将UUID转换为整数键
        int integerKey = uuid.hashCode();

        // 将整数键广播到所有Executor
        Broadcast<Integer> broadcastKey = jsc.broadcast(integerKey);

        // 创建RDD并在每个Executor上使用整数键
        jsc.parallelize(new ArrayList<>()).flatMap(new FlatMapFunction<Object, Object>() {
            @Override
            public Iterator<Object> call(Object o) throws Exception {
                int executorKey = broadcastKey.value();
                // 在这里使用executorKey进行处理
                return null;
            }
        });

        spark.stop();
    }
}
