Just heard from Erik Tryzlaar from Lab41, that a new github open source project called Twill is alive. The project allows for running GraphLab tasks on a Hadoop 2.0 cluster which supports Yarn.
To remind, Pivotal have also their own wrapper which allows for running GraphLab on their Hadoop cluster, as part of their HD project.
A lot of exciting activities from different parties who are helping to make Graphlab Hadoop compatible! We will also release some news from GraphLab about this direction soon.
