求助：Hadoop解壓縮報錯 java.io.IOException: incorrect header check

若有大佬路過，煩請留下隻言片語，小白不勝感激~
源代碼如下：

package com.psy.mr.compress;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.Path;
import org.apache.hadoop.io.IOUtils;
import org.apache.hadoop.io.compress.CompressionCodec;
import org.apache.hadoop.io.compress.CompressionCodecFactory;
import org.apache.hadoop.io.compress.CompressionInputStream;
import org.apache.hadoop.io.compress.CompressionOutputStream;
import org.apache.hadoop.util.ReflectionUtils;

import java.io.*;

public class TestCompress {
    public static void main(String[] args) throws IOException, ClassNotFoundException {
        // 壓縮
//        compress("e:/hello.txt","org.apache.hadoop.io.compress.DefaultCodec");
        deCompresses("e:/hello.txt.deflate");
    }

    private static void deCompresses(String fileName) throws IOException {
        // 1.壓縮方式檢查
        CompressionCodecFactory factory = new CompressionCodecFactory(new Configuration());
        CompressionCodec codec = factory.getCodec(new Path(fileName));
        if (codec == null){
            System.out.println("cannot process this kind of compression method");
            return;
        }
        // 獲取輸入流
        CompressionInputStream cis = codec.createInputStream(new FileInputStream(new File(fileName)));
        // 獲取輸出流
        FileOutputStream fos = new FileOutputStream(new File(fileName + ".decode"));
        // 流的對拷
        IOUtils.copyBytes(cis,fos,1024*1024*5,false);
        // 關閉資源
        IOUtils.closeStream(fos);
        IOUtils.closeStream(cis);

    }

    private static void compress(String fileName, String method) throws IOException, ClassNotFoundException {
        //獲取輸入流
        FileInputStream fis = new FileInputStream(new File(fileName));
        //獲取輸出流
        Class<?> classCodec = Class.forName(method);
        CompressionCodec codec = (CompressionCodec) ReflectionUtils.newInstance(classCodec, new Configuration());
        FileOutputStream fos = new FileOutputStream(new File(fileName + codec.getDefaultExtension()));
        CompressionOutputStream cos = codec.createOutputStream(fos);
        //流的對拷
        IOUtils.copyBytes(fis,fos,1024*1024*5,false);
        //關閉資源
        IOUtils.closeStream(cos);
        IOUtils.closeStream(fos);
        IOUtils.closeStream(fis);
    }
}

然後報錯如下：
