Hi,

You have to specify EdgeInputFormat.

For another class of mine I use the following command (wrting for just 
reference):

hadoop jar 
giraph-examples/target/giraph-examples-1.1.0-SNAPSHOT-for-hadoop-1.0.2-jar-with-dependencies.jar

org.apache.giraph.GiraphRunner 
org.apache.giraph.examples.LinkRank.LinkRankVertex
-vif org.apache.giraph.examples.LinkRank.LinkRankVertexInputFormat
-eif org.apache.giraph.examples.LinkRank.LinkRankEdgeInputFormat
-of org.apache.giraph.examples.LinkRank.LinkRankVertexOutputFormat
-w 1
-vip nodes.txt
-eip edges.txt
-op linkOutput4

You can see the sample EdgeInputFormat on http://bit.ly/174RfHG.
