Description

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.
