I am creating a program to analyze PDF, DOC and DOCX files. These files are stored in HDFS.

When I start my MapReduce job, I want the map function to have the Filename as key and the Binary Contents as value. I then want to create a stream reader which I can pass to the PDF parser library. How can I achieve that the key/value pair for the Map Phase is filename/filecontents?

I am using Hadoop 0.20.2

This is older code that starts a job:

```
public static void main(String[] args) throws Exception {
 JobConf conf = new JobConf(PdfReader.class);
 conf.setJobName("pdfreader");

 conf.setOutputKeyClass(Text.class);
 conf.setOutputValueClass(IntWritable.class);

 conf.setMapperClass(Map.class);
 conf.setReducerClass(Reduce.class);

 conf.setInputFormat(TextInputFormat.class);
 conf.setOutputFormat(TextOutputFormat.class);

 FileInputFormat.setInputPaths(conf, new Path(args[0]));
 FileOutputFormat.setOutputPath(conf, new Path(args[1]));

 JobClient.runJob(conf);
}

```

I Know there are other inputformat types. But is there one that does exactly what I want? I find the documentation quite vague. If there is one available, then how should the Map function input types look?

Thanks in advance!
