Thanks for looking into this...
I am just trying to set things up to begin playing around and i got
the command from http://hadoop.apache.org/docs/r0.18.3/quickstart.html
When i run it, the command simply returns silently no messages on the
console...if you could point me to how to enable and look at logs that
would be helpful..
