Hi Ferenc, I have an Giraph job that outputs from the Computation class as opposed to the MasterCompute because I need to maintain alot of state within VertexValues as opposed to Aggregators. This is one way of outputting results as multiple files. I am assuming that you want to scope output files per sub-graph groupings of vertices, of course. :)
