要使java程序适合map reduce，必须对其进行的最小绝对修改是什么？
这是我的java程序：

import java.io.*;

class evmTest {

public static void main(String[] args) {

    try {

        Runtime rt = Runtime.getRuntime();
        String command = "evm --debug --code 7f00000000000000000000000000000000000000000000000000000000000000027f00000000000000000000000000000000000000000000000000000000000000027f00000000000000000000000000000000000000000000000000000000000000020101 run";
        Process proc = rt.exec(command);

        BufferedReader stdInput = new BufferedReader(new 
             InputStreamReader(proc.getInputStream()));

        BufferedReader stdError = new BufferedReader(new 
             InputStreamReader(proc.getErrorStream()));

        // read the output from the command
        System.out.println("Here is the standard output of the command:\n");
        String s = null;
        while ((s = stdInput.readLine()) != null) {
            System.out.println(s);
        }

        // read any errors from the attempted command
        System.out.println("Here is the standard error of the command (if any):\n");
        while ((s = stdError.readLine()) != null) {
            System.out.println(s);
        }

    } catch (IOException e) {
        System.out.println(e);
    }

}

}

它打印终端的输出，以这种方式呈现：

Here is the standard output of the command:

0x
Here is the standard error of the command (if any):

当然，这是apache示例中最简单的map reduce作业之一：

import java.io.IOException;
import java.util.StringTokenizer;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.Path;
import org.apache.hadoop.io.IntWritable;
import org.apache.hadoop.io.Text;
import org.apache.hadoop.mapreduce.Job;
import org.apache.hadoop.mapreduce.Mapper;
import org.apache.hadoop.mapreduce.Reducer;
import org.apache.hadoop.mapreduce.lib.input.FileInputFormat;
import org.apache.hadoop.mapreduce.lib.output.FileOutputFormat;

public class WordCount {

  public static class TokenizerMapper
       extends Mapper<Object, Text, Text, IntWritable>{

    private final static IntWritable one = new IntWritable(1);
    private Text word = new Text();

    public void map(Object key, Text value, Context context
                    ) throws IOException, InterruptedException {
      StringTokenizer itr = new StringTokenizer(value.toString());
      while (itr.hasMoreTokens()) {
        word.set(itr.nextToken());
        context.write(word, one);
      }
    }
  }

  public static class IntSumReducer
       extends Reducer<Text,IntWritable,Text,IntWritable> {
    private IntWritable result = new IntWritable();

    public void reduce(Text key, Iterable<IntWritable> values,
                       Context context
                       ) throws IOException, InterruptedException {
      int sum = 0;
      for (IntWritable val : values) {
        sum += val.get();
      }
      result.set(sum);
      context.write(key, result);
    }
  }

  public static void main(String[] args) throws Exception {
    Configuration conf = new Configuration();
    Job job = Job.getInstance(conf, "word count");
    job.setJarByClass(WordCount.class);
    job.setMapperClass(TokenizerMapper.class);
    job.setCombinerClass(IntSumReducer.class);
    job.setReducerClass(IntSumReducer.class);
    job.setOutputKeyClass(Text.class);
    job.setOutputValueClass(IntWritable.class);
    FileInputFormat.addInputPath(job, new Path(args[0]));
    FileOutputFormat.setOutputPath(job, new Path(args[1]));
    System.exit(job.waitForCompletion(true) ? 0 : 1);
  }
}

我的问题是-Map简化我在本文顶部共享的java程序最简单的方法是什么？
更新
使用以下命令运行：

$HADOOP_HOME/bin/hadoop jar /usr/local/hadoop/share/hadoop/tools/lib/hadoop-streaming-2.8.1.jar -D mapreduce.job.reduces=0 -input /input_0 -output /steaming-output -mapper ./mapper.sh

导致此错误：

开始在这里遇到问题：

17/09/26 03:26:56 INFO mapreduce.Job: Task Id : attempt_1506277206531_0004_m_000000_0, Status : FAILED
