This causes ArrayIndexOutOfBound Exception which was the reason to generate
empty directory
line.substring(i,2) should be line.substring(i,i+2); as substring takes start
and end index as parameters Thanks,

Hello all,
I had written a kmer mapreduce program in java. There is no error in the
program and while running it creates an output directory in hadoop file
system but that directory is empty.
Please help to resolve this issue.
Input file(test.txt) and kmer.java is attached herewith.

Thanks
Can you attach .java file instead of .class ?

First try:
You should use @Override annotation before map and reduce methods so they
are actually called.
Like this:
*@Override*
public void map(LongWritable k,Text v,Context con)throws
IOException,InterruptedException
{...
Do same for 'reduce' method.

Vandana,
Also, in the code that you attached, I see 2 compilation errors. How is it
even compiling? Or am I missing something here?
1- The 'sum' is not declared in the Map class.
2- The 'sum' in the Reduce class, when written to the context needs to be
IntWritable and not directly an int.
Hi,
Does this even compile? In the mapper the variable sum doesn't seem to be
defined?
con.write(new Text(y), new IntWritable(sum));
