KMeans clustering for more than 5 million vectors

Question

I have hit a real problem. I need to do some Kmeans clustering for 5 million vectors, each containing about 32 cols. I tried out Mahout which requires linux and I am on win

Answer 1

OK, So who ever wants clustering for large scale datasets, the only way of doing so is to use Mahout. IT requires a linux platform. So I had to use virtual box, placed Ubuntu on it and then used Mahout. Its a lengthy procedure to set up Mahout, but the two links that I used are as follows.
