Hello there,
i just downloaded the version 0.6.3, did the configurations and
wanted to run my programs. Previously I was using hama 0.6.0. The
examples are working fine but when I give one jar of mine to be run, I
have the following issue:
- It starts 2 jobs and after the first is completed without doing
anything, the second hangs and prints this:

From what I see, it has to do something either with the setup and bsp
functions or with the reader because there is NullPointerException at
loadVertices.
I don't think it is the first one cause I am using hama Graph.
Any ideas?
Thanks
