Hi.
I checked out and built Giraph for Cloudera CDH5 with Hadoop 2.2.0 using the
following:
git clone git://git.apache.org/giraph.git snapshot_from_git
cd snapshot_from_git
mvn -Phadoop_yarn -Dhadoop.version=2.2.0 clean package -DskipTests
When I run the sample application
org.apache.giraph.examples.SimpleShortestPathsComputation I get the following
exception:
LogType: gam-stdout.log

Here is the command I used to run the application:

giraph-1.1.0-SNAPSHOT-for-hadoop-2.2.0-jar-with-dependencies.jar,giraph-examples-1.1.0-SNAPSHOT-for-hadoop-2.2.0-jar-with-dependencies.jar
What am I doing wrong? Appreciate any suggestions for what to try next.
Thanks.
Stefan
