Hi Sebastian, I am using following command to run my Giraph Application- $HADOOP_HOME/bin/hadoop jar ex-jar/myexample.jar org.apache.giraph.GiraphRunner myVertexClassPackage.MyVertexClass -vif myVertexClassPackage.MyVertexInputFormat -vip /input/input_graph.txt -of myVertexClassPackage.MyVertexOutputFormat -op /output/testOutput -w 1
Thanks.
