> When a user does not explicitly sets the number of BSP tasks in his own jobs the job
will hang forever with this output:
>     11/04/17 20:07:50 INFO bsp.BSPJobClient: Running job: job_201104172007_0001
>     11/04/17 20:07:53 INFO bsp.BSPJobClient: Current supersteps number: 0
> We should provide a check that will reject wrong values: 1 > numOfTasks > numberOfGrooms
(is this upper bound right or can multiple tasks of the same job run on the same groom?)
> This could be implemented in the method "submitJobInternal" of the BSPJobClient. We should
add an info log statement if we changed the value.
