Hi Chahinez,
There is a problem in your configuration parameters.
-vif org.apache.giraph.io.gora.GoraGEdgeEdgeInputFormat
-eof org.apache.giraph.io.gora.GoraGEdgeEdgeOutputFormat
The option <vif> means <Vertex input format> and as you can see you are
using GoraGEdgeInputformat which as you can see is an EDGE input format. A
graph can be represented by denoting the set of vertices with their edges
or the set of edges that join vertices. That is why Giraph gives you the
option to use either of them. So if you want to use the vertex input format
you should use org.apache.giraph.io.gora.GoraGVertexVertexInputFormat or a
class that extends from org.apache.giraph.io.gora.GoraVertexInputFormat.
