Subject pagerank in giraph.
Date Wed, 26 Feb 2014 20:09:01 GMT
  To load and compute the pagerank of the following graph format(common in
social network graphs):

Src_vertex_id_1 Dest_vertex_id_2 Dest_vertex_id_3 (v1->v2, v1->v3)
Src_vertex_id_2 Dest_vertex_id_4 Dest_vertex_id_5 Dest_vertex_id_6 (v2->v4,
v2->v5, v2->v6)

Should I have to convert the above input format into the following so as to
be compatible with giraph?

[Src_vertex1_id_1, 1, [[Dest_vertex_id_2,0],[Dest_vertex_id_3,0]]]
[Src_vertex1_id_2, 1,

I.e, to set initial vertex values to 1 and edge values to 0? Thanks!

  Best Regards,
