Subject StackOverflowError
Date Mon, 02 Dec 2013 15:05:41 GMT
Hi,

I'm trying to run a Giraph Job having 60,000 nodes and 20,000,000 edges
[highly connected].

Cluster consists of 4 nodes each with 17 GB RAM. I'm running only one
worker per node and a master [so that'll be 1 Master & 3 Workers]

I keep getting the java.lang.StackOverflowError in one of the workers.

Here is the log:-
