> 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.
