Subject Re: Problem in running my own giraph program
Date Sat, 26 Oct 2013 19:50:08 GMT
try removing the "-libjars" string. that is necessary if you need
additional jar for your computation class. After the GiraphRunner class,
you should have the name of the computation class (
org.apache.giraph.examples.SimpleShortestPathsComputation in your case).
The rest looks fine for me.
