>
> For near real-time jobs running on hadoop, we want to minimize impact on them
> when rolling restarting tasktrackers. The idea here is to restart
> tasktrackers from jobtracker and selectively choose task trackers according
> to tasks' status on them to do rolling restart, such that the impact on total
> job running time is minimum.
