Hi Sebastian..
Thanks for the links given for big graphs..
Actually I want to tell you something about problem i am facing.
Initially I was working with *hadoop 0.20.203* . I build Giraph there.. it
was running fine.
Now to test very big graph related problem and to compare the performance
, I moved to new system which is of 64 cores and 512 GB memory and 3 TB
storage. Instead to building Giraph in the new system, I just copied
Giraph folder from my previous system to this new system. In this new
system *hadoop version 2.2..0 * . I tried to execute
SimpleSourceShortestPath algo on sample data set. It is throwing following
exception.
I gave following command to execute the job.
hadoop jar

Thanks & Regards
