Hi All, I am a Graduate student. I am working on Hadoop for a college project and have a few question on the hardoop set up.
> I am running hadoop on windows OS with cygin installed. > In eclipse when i open the org.apache.hadoop.example.WordCount example > file, i see a void main written for this class. > so i am trying to run this program from the standalone mode, by passing > the command line arguments. > > 1) Will i be able to run the program this way, because i am running this > trough the windows system.

Please advise as to how i can proceed from here. -- Thanks, Radhika Sridhar
