Hi all, I'm new to Giraph, now I successfully ran my first example by following the instruction on Giraph - Quick Start. However, I met a question when I write my own Giraph code.
In the "quick start", The format of input graph is as following: [0,0,[[1,1],[3,3]]] [1,0,[[0,1],[2,2],[3,1]]] [2,0,[[1,2],[4,4]]] [3,0,[[0,3],[1,1],[4,4]]] [4,0,[[3,4],[2,4]]] But the graphs (like Facebook, twitter social network) datasets downloaded from public websites are in various format. How can I transform a graph into the standard Giraph graph like the above one? For example the WikiTalk graph as blow, which is a directed graph. Directed edge A->B means user A edited talk page of B. # FromNodeId ToNodeId 0 1 2 1 2 21 2 46 2 63 2 88 2 93 2 94 2 101 2 102 2 103 2 116 2 119 2 125 Regards, Ralph
