Hey,
I only have 1 job. I don't know why it starts 2 jobs.

Hi,
this seams to be a problem with the input. If you say that your first job
produces nothing, then the second job is getting null input and this is
probably why you get this error. I think your problem might be in your first
job.
Can you separate the jobs and investigate why this is happening? Or can you
create a custom input for your second job and run it with a specific input to
be sure that the problem is there?
Cheers,
Anastasis

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
