Hi, Unfortunately we chose to remove the graph algorithms from Mahout for the next version. You might want to have a look at Apache Giraph which offers an easy way to implement graph algorithms.
RandomWalkWithRestart is essentialy the same as PageRank with the difference that the teleportation will only hit the source vertex of the walk not a random vertex in the graph. http://www.cs.cmu.edu/~ukang/papers/PegasusKAIS.pdf contains a short description.
