Hi, I am using version 0.2 of giraph and version 0.20.203 of hadoop. I would like to run the SimpleShortestPathsVertex example, and so I tried the command in the documentation ( https://cwiki.apache.org/confluence/display/GIRAPH/Shortest+Paths+Example):
hadoop jar ~/giraph/giraph-examples/target/giraph-examples-0.2-SNAPSHOT-for-hadoop-0.20.203.0-jar-with-dependencies.jar org.apache.giraph.examples.SimpleShortestPathsVertex graph output 0 3 but I get: Exception in thread "main" java.lang.NoSuchMethodException: org.apache.giraph.examples.SimpleShortestPathsVertex.main([Ljava.lang.String;) Indicating that the class has no main method. The documentation ( https://cwiki.apache.org/confluence/display/GIRAPH/Shortest+Paths+Example) in fact states that this is the expected behavior in giraph 0.2 because it must be run with ToolRunner, but I don't see any instructions for executing SimpleShortestPathsVertex using ToolRunner. This is the first time that I am running hadoop and giraph, so I am probably missing something here, and any help would be greatly appreciated. Best, Jonathan
