Subject Issue running Giraph on more mappers
Date Thu, 29 Nov 2012 06:09:07 GMT
Hi,
I am trying to run this workflow which uses Giraph.
I am able to succesfully run the Giraph job when I use lesser no. of mappers  and less data.
But it fails for more mappers.
This is what the logs say for master and worker nodes:

Master Node:
