Hello, I am new to Giraph and was just wondering how one could retrieve and display the certain global values/statistics that the aggregators keep track of. What classes and methods would I use, and would this be done in a class that extends VertexOutputFormat, or would it be done elsewhere?
As an example, in the provided SimplePageRankComputation in org.apache.giraph.examples, there are three aggregators: sum, min, and max. I would like to display all of their final values (after the final superstep) in some way, such as writing them to a text file. -- Kyle Orlando Computer Engineering Major University of Maryland
