Hi Bharath
        You could be getting detailed metrics on a per job basis from the jobtracker web UI


If you drill down you can get still further details on task levels .

Subject: Tracking Job completion times

Hi all,

I'd like to log and monitor average job completion times on hadoop.
(For example, wall time from the perspective of the JobTracker)
What might be the best way to do this?

I see a lot of metrics exported through the metrics2 interface:
are job completion times part of this? Is there documentation I could read
to understand the exported jobtracker/tasktracker metrics?

Thanks a lot!
Bharath Ravi
