> Key: HADOOP-98
> URL: http://issues.apache.org/jira/browse/HADOOP-98
> Project: Hadoop
> Type: Bug
> Components: mapred
> Versions: 0.1
> Reporter: Owen O'Malley
> Assignee: Owen O'Malley
> Fix For: 0.1
> Attachments: task-counter.patch
>
> When a heatbeat comes in from a task tracker, the job tracker just adds the
> number of currently running maps and reduces. The jobs from the previous
> heartbear are never subtracted. This causes the scheduling to misjudge the
> "loading" levels of the task trackers.
