toString();
}
Again my output is empty. 3.Inorder to emit a key too as custom datatype
CompareTo is neccessary right .
4.so what should i include in that methods CompareTo,hashcode,equals and
what are these methods intended for.
Any Idea.Pls suggest a solution.

I am emiting two 2D double array as key and value.I am in construction of
my WritableComparable class.
*public class MF implements WritableComparable{
/**
* @param args
*/private double[][] value;
public MF() {
// TODO Auto-generated constructor stub
}
public MF(double[][] value) {
//
2d double array is a matrix.so i should be able to emit the entire matrix .
Can any one suggest how to write a custom datatype
