I'm sorry. I copied the command line here before wrongly. What I am actually doing is:
hadoop jar hadoop-0.20.203.0-jar-with-dependencies.jar org.apache.giraph.examples.SimpleShortestPathsVertex shortestPathsInputGraph shortestPathsOutputGraph 0 3 And I got that error that I mentioned before. 2012/9/26 André Kelpe <[email protected]> > Hi Rodrigo, > > if i am parsing your commandline right, you are missing the jar > argument to the hadoop command. > > It should be something like > > hadoop jar my-fancy-giraph.jar --some param --some-other param > > HTH > > --Andre > > 2012/9/26 rodrigo zerbini <[email protected]>: > > Hello everybody. > > > > My name is Rodrigo and I'm just starting a scientific initiation on graph > > processing sys tems.
