让Lucene能搜索HDFS下的索引：

    public static void main(String[] args) throws IOException 
    {
        Configuration conf = new Configuration();   
        FileSystem fs = FileSystem.get(conf);
        FsDirectory dir=new FsDirectory(fs, new Path("nutindex/0/"), false, conf);
        IndexReader reader = IndexReader.open(dir);
        System.out.println(reader.numDocs());
        for(int i=0;i<reader.numDocs();i++)
        {
           System.out.println(reader.document(i).get("id"));
        }
        reader.close();
   }
