Which component manages slow tasks?
I am interested in which component of hadoop and how is managed slow task
execution.

Is this a tasktracker, jobtracker or a scheduler?

In fairscheduling (0.20.205) there exist a preemption mechanism but it just
handles min and fairshares and kills last submited tips..

Thanks.
