Hi Vivek, Sorry for the hasty response, I assumed the quick start guide covered that (I guess it doesn't). What you need to do first is put all of your compiled code into a jar file. Then, you'll be utilizing the hadoop option -libjars. You also need to make sure that you set the hadoop classpath to include the giraph jar you are using as well as your own jar. I actually asked a similar question not too long ago; prior to this, I was just combining everything into one jar.
Your code should pretty much follow this format, which is copied and paster from a previous response by Claudio: export HADOOP_CLASSPATH="giraph.jar:your.jar" hadoop jar giraph.jar org.apache.giraph.GiraphRunner [ -D option ]* -libjars your.jar your.package.ComputationClass [ GiraphRunner option e.g. -vip -vif etc. ]* On Fri, Aug 23, 2013 at 2:51 PM, Vivek Sembium <vivek.semb...@gmail.com>wrote: > Thank You for your response.
