Hi, You built Giraph for the Hadoop version 1.2.1 which is evident from your command line *hadoop jar /usr/local/giraph/giraph-examples/target/giraph-examples-1.1.0-SNAPSHOT-for-hadoop-1.2.1-jar-with-dependencies.jar *
You have the build Giraph against the Hadoop version you'll be using. If you are using Hadoop 2.4.0, the command to build would be *mvn -Phadoop_2 -Dhadoop.version=2.4.0 -DskipTests ...* or *mvn -Phadoop_yarn -Dhadoop.version=2.4.0 -DskipTests ...* You can find this in the *README* file from Giraph trunk Hope this helps.
