Subject Re: Newbie problem - I can't run the Shortest Paths Example

Yes, it was another typo. Sorry!
I must be distraught to have commited so many typos.

Well, the command line below works for you?

hadoop jar
giraph-0.2-SNAPSHOT-for-hadoop-0.20.203.0-jar-with-dependencies.jar
org.apache.giraph.examples.SimpleShortestPathsVertex
shortestPathsInputGraph shortestPathsOutputGraph 0 3
