Subject Re: giraph - problem running shortest path example
Date Sat, 19 Jan 2013 15:27:24 GMT
Hi

I still trying to run the giraph shortest path example.
So far I resolved most of the WARN from the hadoop userlogs files

But I still got this problem shown on the terminal:

And in the logs file I funded this FATAL...

I hope you can help my to solve this problem.
till now I tried to run this on a pseudo distributed cluster and also on my
real working Hadoop cluster, and got the same error.

Thanks for the help
