(1) Mahout 0.7 is not supported anymore and u shouldn't be using it.
(2) To get ur code to compile with 0.9 remove the DistanceMeasure arguments
in ur call to KMeansDriver.run()
WeightedVectorWritable was replaced by WeightedPropertyVectorWritable
in 0.9.
So change the line of code to WeightedVectorWritable value = new
WeightedPropertyVectorWritable();
It would be helpful if u could post the compilation errors u r seeing
to better help u.
