我尝试在一个完全不包含hadoop的环境中运行sparkml算法。
我还没有从教程和其他帖子中弄清楚这是否可行：
我可以不使用任何版本的hadoop和hdfs运行spark吗？或者我应该安装hadoop来激发灵感？
运行spark shell时，我收到以下消息：

C:\spark-2.2.0-bin-without-hadoop\bin>spark-shell

下面是我的示例程序：

package com.example.spark_example;
import org.apache.spark.SparkConf;
import org.apache.spark.api.java.JavaRDD;
import org.apache.spark.api.java.JavaSparkContext;
import org.apache.spark.api.java.function.Function;
public class Main {
  public static void main(String[] args) {
    String logFile = "C:\\spark-2.2.0-bin-without-hadoop\\README.md"; // Should be some file on your system
    SparkConf conf = new SparkConf().setAppName("Simple Application");
    JavaSparkContext sc = new JavaSparkContext(conf);
    JavaRDD<String> logData = sc.textFile(logFile).cache();
    long numAs = logData.filter((Function<String, Boolean>) s -> s.contains("a")).count();
    long numBs = logData.filter((Function<String, Boolean>) s -> s.contains("b")).count();
    System.out.println("Lines with a: " + numAs + ", lines with b: " + numBs);
    sc.stop();
  }
}

导致以下异常：

17/08/10 15:23:35 WARN NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
17/08/10 15:23:35 ERROR Shell: Failed to locate the winutils binary in the hadoop binary path
