Hi Martin

I don't think that there are problems with comparing and sorting Text 
writables as Hadoop is basically a big external sorting system.

I'm not sure I understand your edge input reader, it looks very complex, 
maybe there's a bug somewhere. You could try to preprocess your data 
using Hadoop so that you can use a simple VertexInputFormat and see if 
your problems still occur.
