Hey Alex,
Our cluster uses Cloudera for Hadoop admin stuff. To the best of my

I am having some trouble getting these examples running. I’m using giraph
version 1.1.0 and hadoop 0.20.2. I am using the following json file as
input:
[0,0,[[1,1],[3,3]]]
[1,0,[[0,1],[2,2],[3,1]]]
[2,0,[[1,2],[4,4]]]
[3,0,[[0,3],[1,1],[4,4]]]
[4,0,[[3,4],[2,4]]]
The command I use is:
hadoop jar
