Support running multiple DataNodes/TaskTrackers simultaneously in a single node
-------------------------------------------------------------------------------

                 Key: HADOOP-5945
                 URL: https://issues.apache.org/jira/browse/HADOOP-5945
             Project: Hadoop Core
          Issue Type: New Feature
            Reporter: He Yongqiang


We should support multiple datanodes/tasktrackers running at a same node, only if they do
not share same port/local fs dir etc. I think Hadoop can be easily adapted to meet this. 

I guess at first and the major step is that we should modify the script to let it support
startting multiple datanode/tasktracker daemons in a same node.
