I think you may have added the same vertex 2x? That being said, I don't
see why the code is this way. It should be fine. We should file a JIRA.

Thanks, Lukas!
I think the reason of this exception is that I run the job over part
of the graph where some target ids do not exist.

Hi,
Do you use partition balancing ?

I got this exception when I ran a Giraph-1.0.0 PageRank job over a 60

Does anyone know what is the possible cause of this exception?
Thanks!
