IntIntNullIntTextInputFormat in the examples package (extending
TextVertexInputFormat as David suggests) is very similar to what you
need I think, although the types might be different for your
application. You can start with that perhaps.

The easiest thing to do is to extend text vertex or/and textvertext
input format and/or the record reader. The record reader will give
you the vertices you want. Look at the record reader for
textvertexinputformat. It's an innerclass on this format class.

Subject: how to use SimplePageRankVertex
Date: Sat, Feb 18, 2012 9:08 am
I am planning to use giraph for network analysis. First I am trying to
fully understand SimplePageRankVertex implementation and modify in
order to serve my needs.
I have a question about example,
What is the expected input format for SimplePageRankVertex, I couldn't
understand the input format although SimplePageRankVertexReader class
has few lines.
My input file is contains of rows such as:
Each row represents a relation between two users,
*"usera,userb"* means that *"usera is clicked userb's profile" *
Is it possible to make social network analysis over such kind of data
I will be glad if you can give advices..
thanks in advance
