I've been trying to work through the Quick Start examples and adapting
it to my local installation, I'm running Hadoop 2.0.5-alpha across 4
machines.
I've done the checkout from github
sudo git clone https://github.com/apache/giraph.git
Applied the patch to ZooKeeperManager
http://www.mail-archive.com/user@giraph.apache.org/msg00945/check.diff
Fixed the catching of the exception in
giraph-core/src/main/java/org/apache/giraph/job/HaltApplicationUtils.java
Then building with
mvn clean install -Phadoop_2.0.3 -DskipTests
Then when I go to run the examples, I set -w 4 because I am running a
split master setup. Unfortunately this leads to:
lairdm@x007:/opt/giraph$ $HADOOP_HOME/bin/hadoop jar

I'm not sure what parameters I need to give giraph to signal not to use
LocalJobRunner. Does anyone have a suggestion?
Thanks.
