Why am i unable to getFileName & display it in format (Word Filename Counts) In Hadoop?

Question

The Input is a text file named Wiki-micro.txt ... The word count program is running fine .. What i need is to modify it & change its output format from (Word count) to (Word####Filename count) I want my output in format (Word#####Filename count), Can you please let me know where i am going wrong? I used the Input Split but its not working .. Kindly, help me in that.

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

  private static final Pattern WORD_BOUNDARY = Pattern .compile("\\s*\\b\\s*");

  public void map( LongWritable offset,  Text lineText,  Context context)
    throws  IOException,  InterruptedException {

     String line  = lineText.toString();
     Text currentWord  = new Text();
     InputSplit input_split = context.getInputSplit();
     String FName = ((FileSplit) input_split).getPath().getName();

     for ( String word  : WORD_BOUNDARY .split(line)) {
        if (word.isEmpty()) {
           continue;
        }
        currentWord  = new Text(word);
        context.write(currentWord, one);
        context.write(new Text(FName), one);
     }
  }

}

Not sure, but what happens if you replace the last 3 lines:

        currentWord  = new Text(word);
        context.write(currentWord, one);
        context.write(new Text(FName), one);

with

        currentWord  = new Text(word + "####" + FName);
        context.write(currentWord, one);
        context.write(new Text(FName), one);
