Subject Error - Messages must never be behind the vertex in ID! Current Message ID: 2 vs. 20
Date Thu, 08 Aug 2013 10:55:38 GMT
Hi,

I followed the SSSP example, GraphJob example and getting following error:

What could be the reason I am getting this error.

I am able to run the code in eclipse/standalong environment. However, when
I try to run with hama/hadoop pseudo distribution mode it fails.

Thanks,
Mahesh Babu
