> repeatedly blacklisted tasktrackers should get declared dead

> Key: HADOOP-4305
> URL: https://issues.apache.org/jira/browse/HADOOP-4305
> Project: Hadoop Core
> Issue Type: Improvement
> Components: mapred
> Reporter: Christian Kunz
> Assignee: Amareshwari Sriramadasu
> Fix For: 0.20.0
>
> Attachments: patch-4305-0.18.txt, patch-4305-1.txt, patch-4305-2.txt
>
>
> When running a batch of jobs it often happens that the same tasktrackers are
> blacklisted again and again. This can slow job execution considerably, in
> particular, when tasks fail because of timeout.
> It would make sense to no longer assign any tasks to such tasktrackers and to
> declare them dead.
