Maria Stylianou commented on GIRAPH-644:
----------------------------------------

So, I created a VertexValueFactory as you said, but I get the following exception:

> Vertices that get created by receiving a message (and not created on superstep 0) do
not get the value initialized by MAX_VALUE.
> This happens when the vertex is not given on the first column in the input file. This
means that the vertex is not created at the beginning but only when it receives a message,
hence the initialization call is not executed and the vertex value is set to 0.
