本地文件系统上的Spark独立模式

Question

为什么Spark java驱动程序会强制我安装winutils.exe，它被认为是Hadoop二进制文件，如果我想在本地非HDFS文件系统上以独立模式运行它？

import org.apache.spark.api.java.*;
import org.apache.spark.SparkConf;

public class Main {
    public static void main(String[] args) {
        String testFile="test.iml";
        SparkConf conf=new SparkConf().setAppName("Test application").setMaster("local[*]");

        JavaSparkContext sparkContext=new JavaSparkContext(conf);

        JavaRDD<String> logData=sparkContext.textFile(testFile).cache();

        long numAs=logData.filter((s)->s.contains("a")).count();
        long numBs= logData.filter((s)->s.contains("b")).count();

        System.out.println(numBs);
        System.out.println(numAs);

    }
}

错误消息

ERROR Shell: Failed to locate the winutils binary in the hadoop binary path
java.io.IOException: Could not locate executable null\bin\winutils.exe in the Hadoop binaries.
