Subject Re: Shortest Paths Example
Date Mon, 01 Oct 2012 01:58:35 GMT
I was running the command in the directory named trunk. I made another
attempt trying to run it in the directory named target, where
giraph-0.2-SNAPSHOT-for-hadoop-0.20.203.0-jar-with-dependencies.jar is.

When I tried

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

I got this:

Exception in thread "main" java.lang.NoSuchMethodException:
org.apache.giraph.examples.SimpleShortestPathsVertex.main([Ljava.lang.String;)
    at java.lang.Class.getMethod(Class.java:1605)
    at org.apache.hadoop.util.RunJar.main(RunJar.java:150)

When I tried

hadoop jar
giraph-0.2-SNAPSHOT-for-hadoop-0.20.203.0-jar-with-dependencies.jar
org.apache.giraph.GiraphRunner
org.apache.giraph.examples.SimpleShortestPathsVertex -if
org.apache.giraph.lib.JsonBase64VertexInputFormat -ip
shortestPathsInputGraph -of
org.apache.giraph.lib.JsonBase64VertexOutputFormat -op
shortestPathsOutputGraph -w 3

I got this:

Exception in thread "main" java.lang.ClassNotFoundException:

What do these errors mean?
Did anyone have success in running this example?
If yes, could you help me, please?
