With a super quick look, so i might be completely wrong, this looks like you're running a different hadoop locally and on your test. Is there any chance you're not using hadoop non_secure locally but you're in your distributed mode? On Fri, Dec 23, 2011 at 10:49 AM, Sebastian Schelter

Shouldn't be the case, I always use 0.20.203... I also implemented a very similar algorithm to find all connected components in a graph and that one worked fine. --sebastian On 23.12.2011 11:07, Claudio Martella wrote: With a super quick look, so i might be completely wrong, this looks like

I'm extending org.apache.giraph.graph.Vertex directly. I also created unit tests for the serialization of the Writables (writing them to a byte array and reading them back) without finding something. Thank you for the advice however, I'll continue searching :) --sebastian On 23.12.2011 18:14,
