Remove 'port rolling' from Mini{DFS|MR}Cluster
----------------------------------------------

                 Key: HADOOP-1085
                 URL: https://issues.apache.org/jira/browse/HADOOP-1085
             Project: Hadoop
          Issue Type: Bug
          Components: test
    Affects Versions: 0.12.0
            Reporter: Arun C Murthy
         Assigned To: Arun C Murthy
            Priority: Critical
             Fix For: 0.12.1


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.
