Summary: Rolling Restart Tasktrackers from JobTracker
Key: MAPREDUCE-5370
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5370
Project: Hadoop Map/Reduce
Issue Type: Task
Reporter: Cindy Li
Priority: Minor
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.
