This is my own Graph package. The most of the stuff in here was from my GSoC2012 repository here. I wanted to get out all the batch related things that I featured on my blog, like mindist search and pagerank. But I have seen that my sequential part of the library is pretty damn bad, so I decided to make it cool and more generic.
This repository will also feature many interesting other graph algorithms, in either MapReduce, BSP or a sequential version.
Since I am Apache committer, I consider everything inside of this repository licensed by Apache 2.0 license, although I haven't put the usual header into the source files.
If something is not licensed via Apache 2.0, there is a reference or an additional licence header included in the specific source file.
You can simply build with:
mvn clean package install
The created jar contains debuggable code + sources.
