> Key: HADOOP-182
> URL: http://issues.apache.org/jira/browse/HADOOP-182
> Project: Hadoop
> Type: Bug
> Components: mapred
> Versions: 0.1.1
> Reporter: Owen O'Malley
> Assignee: Owen O'Malley
> Fix For: 0.2
> Attachments: lost-tracker.patch
>
> When a Task Tracker is lost (by not sending a heartbeat for 10 minutes), the
> JobTracker marks the tasks that were active on that node as failed. There are
> two issues:
> 1. No task from a completed or failed job should be modified.
> 2. No reduces should be marked as failed, since their output is in dfs and
> therefore not only on the dead node.
