GPL-licensed kfs0.3 for building mahout
Hi,
I examined all the jar files needed for building mahout-0.2 jar. There is one jar file called kfs-0.3.jar which is GPL-licensed. I am not an expert on open source licenses, but my understanding is that GPL is viral. Mahout itself is licensed under Apache License, but does its dependence on this GPL-licensed jar file contaminate itself? This issue seems to also be relevant for Hadoop since Hadopp seems to rely on this kfs-0.3.jar too.
Is there any way to build mahout-0.2 without relying on kfs-0.3.jar?
Thanks so very much.

There are a number of jars that were included in the hadoop 0.2
release because they are dependencies of hadoop. Many of these are
optional jars -- they are not actually needed to run hadoop. Things
like kfs and jets3t for example are libraries that are used to run
hadoop on filesystems other than hdfs.
License aside, they are not required for the build. They have been
explicitly excluded as dependencies in HEAD, for the case of
hadoop-0.2 you can comment out the dependency from the pom, and
perform the build without them.

--> Really? From what I could find, it's under Apache 2.0:
Sorry, did I get this wrong? This is where I found the information
http://www.filewatcher.com/p/kfs-0.3.4-280.i586.rpm.211816/HEADER.html
Is this the jar file used in Mahout?
Thanks,
James

Really? 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)

It seems that I got the wrong KFS. I guess the correct one used in Mahout is
http://sourceforge.net/projects/kosmosfs/
Which is licensed under Apache 2.0
Sorry for the confusion.
James

Really? 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)
