Subject Re: Running Giraph-854 SimpleShortestPathsComputation
Date Thu, 27 Feb 2014 10:00:48 GMT
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.
