Java 杀死Hadoop 2.2.0配置弃用信息消息的确切步骤

这个问题类似于，但是这个问题的答案并没有解决这个问题，所以我要求在这个问题上采取具体步骤，并提供一个具体的例子

考虑以下简短的仅地图程序：

import java.io.IOException;
import java.util.*;

import org.apache.hadoop.fs.Path;
import org.apache.hadoop.conf.*;
import org.apache.hadoop.io.*;
import org.apache.hadoop.mapreduce.*;
import org.apache.hadoop.mapreduce.lib.input.*;
import org.apache.hadoop.mapreduce.lib.output.*;
import org.apache.hadoop.mapreduce.lib.*;
import org.apache.hadoop.util.*;


public class Foo {

    //     KEYIN,VALUEIN,KEYOUT,VALUEOUT
    public static class Map extends  Mapper<LongWritable, Text, Text, IntWritable> {
        private final static IntWritable one = new IntWritable(1);
        private Text word = new Text();

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

    public static void main(String[] args) throws Exception {
        org.apache.hadoop.mapreduce.Job job = Job.getInstance();
        job.setJarByClass(Foo.class);
        job.setInputFormatClass(TextInputFormat.class);
        job.setOutputFormatClass(TextOutputFormat.class);
        job.setMapperClass(Map.class);

        job.setMapOutputKeyClass(Text.class);
        job.setMapOutputValueClass(IntWritable.class);

        FileInputFormat.addInputPath(job, new Path(args[0]));
        FileOutputFormat.setOutputPath(job, new Path(args[1]));
        System.exit(job.waitForCompletion(true)?0:1);
    }
}

使用下面的命令行，假设

输入包含上面的输入

hadoop jar Foo.jar Foo Input Output 

将显示以下消息：

上面的示例只使用了
org.apache.hadoop.mapreduce
，我使用了链接到它的powerpoint

到底需要更改什么（在此代码中或在
/etc/hadoop
中）才能使弃用消息消失？
在Apache hadoop的更高版本中已修复-

您可以升级您的Apache Hadoop集群，或者应用补丁并重新构建它。
我一直在关注这个错误。我的分析是，配置类本身正在使用不推荐的包。换句话说，这不是你的错，是Hadoop的错。这种情况经常发生。
