I happen to like the way MiniDFSCluster works. I don't have to worry about modifying configs
to get it to work. As I am building applications that run on top of MiniDFSCluster the status
quo is a big win for me.

> The rolling of ports in these 2 clusters lead to a lot of timing issues and failed test
cases; as witnessed in our patch process.
> The way around is to let the OS pick the port for the NameNode/JobTracker and let the
the DataNode/TaskTracker query them for the port to connect to and then use that port.
