Hi Ryan,
Before running the job, you need to set Vertex and input/output format
classes on it. Please take a look at one of the benchmarks to see how to
do that. Alternatively, you can try using GiraphRunner, where you pass
these classes as command line arguments.

Ok, I've been looking at the PageRankBenchmark. There's a lot going on
in there...
It looks like the minimum amount of stuff I need to run a do-nothing
job is what I've got below.
But now it's telling me that (and PageRankBenchmark doesn't have the
word output anywhere).

Ok, ignoring everything about I/O I can run the below code.
But then it hangs at 0% reduce forever

Hi Ryan:
I got that same error and discovered that I have to start a zookeeper
instance. What I did was to download Zookeeper, write a new zoo.cfg file
under conf directory with the following:
dataDir=/home/user/zookeeper-3.4.5/tmp
clientPort=2181
Also I added some lines in Hadoop's
Ok great, thanks. I've been working with 0.1, I can get things to
compile (see below code) but they still are not running, the maps hang
(also below). I have no idea how to fix it, I may consider updating
that code I have that compiles to 0.2 and see if it works then. The
only difference I can see
Your best bet is to look over the two code components that users most often
have to tweak or implement to write application code. That is, the Vertex
implementations in examples/ and benchmark/ and the IO formats and related
goodies like RecordReaders etc. that are mostly in the io/ dir. You might
