Hi All,
I have been going through many forums and hadoop docs in understanding the architecture/concepts on "how the jobs are submitting in hadoop  and how these spawn map and reduce jobs, so how to know that it requires additional slave nodes to be added to process the job".

Please provide the information on this.

Thanks in advance.
