Hi Alexander,
what do you use as type for your vertex ids? It looks that you are
trying to use longs, while IntIntNullTextInputFormat only provides ints,
that could be the error.

The input file is here (just for testing):
[hduser@localhost ~]$ $HADOOP_HOME/bin/hadoop dfs -cat
/user/hduser/input/test
0 1
1 0
Could you please help with this issue?
Best,
Alex
