metis & nometis are the same, hash does not work #3

Hi,

I noticed that both metis & nometis results in the same partitioning while the hash partitioning results on some error!

If you are using mesh graph, since it is in a mesh structure, both metis and mesh partitioner will return the same result. In another graph, mesh partitioner will not be much different from hashing, and metis partitioner will require you to first use metis package to partition your graph.

 I thought hash partitioner was also working but I need to check again what might be the reason.
