Hi Claudio,
I think I have fixed the problem.
HBase runs with its own copy of ZooKeeper which listens on port 2181. So,
when I tried to start ZooKeeper for Giraph it also tried to listen on port 2181
and found it was already in use, and then it terminated - which is why Giraph
failed. If I stop the HBase daemons (including its copy of ZooKeeper) then
Giraph runs fine.
Essentially there is a conflict between running ZooKeeper for Giraph, if
there is already ZooKeeper running for HBase.
I will try the patch and get back to you.
Thanks for all your help,
Ken

try with the attached patch applied to trunk, without the mentioned -D
giraph.zkManagerDirectory.

can you try defining the zookeeper manager directory from the command line?
like this -D giraph.zkManagerDirectory=/path/in/hdfs/foobar
you'll have to delete this directory by hand before each job. Just to see if it
solves the problem. Then I could know how to fix it.

The process listening on port 2181 is 2892, which turns out to be HBase.

So I am not sure what my zookeeper client is connecting to. It seems to be
connecting to a zookeeper server but when I do 'ps' I cannot see a zookeeper
server running.
Here is my zoo.cfg file,
