Re: Completing betweeness on giraph

Hi Apostolos, What exactly is not working probably when overriding messages and vertex values? I haven't used Giraph in a while but these seem like minor configuration issues. About the algorithm: You're right it's possible to do bc in Giraph but as Claudio said and unless I misunderstood your a

Betweenness on giraph

In the past day, I am struggling on completing calculating Betweeness for a graph. I have uploaded my work in on github slash koutras slash gb. The things I had found difficulty so far is not the algorithm by itself that is the brande's algorithm,but integrating the following things. 1) overridi

Re: Completing betweeness on giraph

i don't think the point is whether following your approach, which is a concatenation of SSSP, this is possible, but whether given the the sizes of graphs your approach is actually feasible. About your questions, you have to implement a type for your Vertex Value and one for the Message, and make s
