--------------------------------------------

Hi Arun,

I am not very old with hadoop So I have two questions.

1. Why do we need more than one datanode and nodeManager in a single node setup.?
2. Is there a standard documentation to do it? Because I was getting bind exceptions while
trying to start two datanodes. Is it configurable somewhere? Or Can I figure it out myself.


I have already improved the scripts with some enhancements. And was thinking having debug
also as an option in it will make them more useful. Again It would be helpful if you can refer
me to some standard doc for that. 

Thanks
