That's a good point, can you open a Jira issue for that? Maybe we should
use some annotation like @Nullable to mark parameters that can be null
to make it easier to avoid forgetting checks in the implementing code.

This looks like the code tries to invoke a no-arg constructor of
ArrayWritable (which doesn't exist AFAIK). Do you use a custom
writable? It needs to have a working no-arg constructor.

I wonder if Giraph is compiled with the correct Hadoop
Hi everybody,
I'd like to announce the 'Parallel Processing beyond MapReduce' workshop
which will take place directly after the Berlin Buzzwords conference (
http://berlinbuzzwords.de/ ).
This workshop will discuss novel paradigms for parallel processing
beyond the traditional MapReduce
presentations - from Germany to evangelize Hadoop.
Speaker: Sebastian Schelter
Session:
Introducing Apache Giraph for Large Scale Graph Processing
Web and online social graphs have been rapidly growing in size and scale
during the past decade. Processing such graphs which consist of millions
of vertices
Here are the slides of my talk Introducing Apache Giraph for Large
Scale Graph Processing at the Berlin Hadoop Get Together yesterday:

I reused a lot of stuff from Claudio's excellent prezi
be good to add at

! Will these be similar to the 'Parallel Processing beyond
MapReduce' workshop after Berlin Buzzwords? It would be good to add at
leaset one of them to the page.

Hi,
you are completely right. I also started implementing RWR today
coincidently, could you file a JIRA ticket for RWR? I would attach my
work done so far and we could work a little on the code.
I think that a lot of things need improvement in the PageRank/RWR
implementation, e.g. stuff like the

That would avoid throwing an exception, but I am not sure it is
actually the best thing to do.
