Subject SimpleShortestPathsVertex does not work when compiled separately
Date Tue, 24 Jul 2012 01:32:31 GMT
Hi,

I created a new test project and copied the code from
SimpleShortestPathsVertex.java file (org.apache.giraph.examples) into it.
But when I run it, it gives me java.lang.ClassNotFoundException. However,
if I run the same program from the  giraph-0.1-jar-with-dependencies.jar,
it runs just fine. Following is the relevant information :

Hadoop version: hadoop-1.0.3 (running in pseudo distributed mode)
giraph version: giraph-0.1
jar created with Eclipse 3.3.1
Output:

I have checked inside the test/giraph folder of the test.jar file. It
contains the class
SimpleShortestPathsVertex$SimpleShortestPathsVertexOutputFormat.
Any help will be appreciated.

Regards,
Kaushik
