http://sourceforge.net/projects/kosmosfs/ Which is licensed under Apache 2.0 Sorry for the confusion.

From what I could find, it's under Apache 2.0: http://blog.kosmix.com/kosmix-technology/kosmos-filesystem-release/ Though it seems odd that the jar is in the org.apache.mahout.kosmofs groupId, vs. org.kosmix (with artifactId of kosmosfs) -- Ken > I am not an expert on open source licenses, but my understanding is that GPL > is viral.
