Hi ! I am interested in understanding the execution flow of the jobtracker, tasktracker and in particular schedulers. I have imported the Hadoop code as a project in the eclipse and could build it and ran some wordcount application in debug mode. I am able to understand the flow from job submission to job completion but not the role of Jobtracker and Taskracker in job execution. How do i know it ? Which applications should i run to know them?
Regards, Arun
