Suraj Menon updated HAMA-610:
-----------------------------

    Attachment: HAMA-610.patch

Please review the patch but DO NOT commit this patch. Once approved, I shal commit it to the
HAMA-505-branch and then merge it to trunk. 

The patch provides an example Data-Locality scheduler we had till date. Better schemes to
be implemented in future.

> With this feature, BSP Job Submission could define a task-allocation strategy per job
depending on the nature of the job. This allocation strategy should be usable by the scheduler
to find the grooms to allocate tasks to. The allocation strategy should get a list of resource
objects and provide a list of grooms such that we could schedule the tasks on grooms that
has the specified resources.
