relationship final in kmeans

Hello,
After the execution of k-means in mahout, read the contents of files /
clusteredPoints and / cluster-*-final. I'm using the command clusterdump.
In cluster-*-final the number of objects in the group doesn't match what I
see in the file clusteredPoints.
I wonder how I can get the relationship <group, object> final, in the order in
which objects are in my initial database.

Thank's,
Pricila
