As you might know I recently started an experimental graph mining module. I was already concerned at the beginning of this whether MapReduce is really a suitable platform for (most) graph algorithms.
I'm not content with the performance of the algorithms after some testing and I'm pretty sure the future of large scale graph processing is not on MapReduce (but hopefully on a Pregel like platform such as Giraph). As we're currently removing clutter and trying to concentrate on the core algorithms, I suggest to remove all graph algorithms with the exception of PageRank. If no one objects with this, I'll start the cleanup in a few days. --sebastian
