Thank you for your answers. That’s mean that I have to download hadoop (0.20.204) and then? Because for the moment I'm using only mahout libs.

I think Mahout 0.7 depends on Hadoop 0.20.204, so you will get the permissions error on Windows and you will get the permissions issue from that version onwards (not sure if it 2.0.0-alpha falls into this group). There is a workaround for it, but it is quite convoluted.
