Any updates!! ---------- Forwarded message ---------- From: kartheek muthyala <[email protected]> Date: Fri, Sep 16, 2011 at 8:38 PM Subject: Job Scheduler, Task Scheduler and Fair Scheduler To: [email protected]
Hi all, Can any one explain me the responsibilities of each scheduler?. I am interested in the flow of commands that goes between these scheduler. And if any one have any info regarding how the job scheduler schedules a job based on the data locality?. As of I know, there is some heartbeat mechanism that goes from task scheduler to job scheduler and in response job scheduler does something here to find out the node where the data is more closely located and schedules the task in that node. Is there an elaborate way of explanation around this area?. Any help will be greatly appreciated. Thanks and Regards, Kartheek.
