Resolution: Incomplete
At this point, lots of have changed have happened. So closing this as stale.

> We are running a big job on our cluster. There are about 400 reducers. Around
> 361 reducers finished successfully while the last batch of 39 reducers all
> failed roughly around the same time. After examining the log files, the
> following error info was found 858 times for a single tasktracker:
> 2008-04-21 02:42:45,368 WARN org.apache.hadoop.mapred.TaskTracker:
> getMapOutput(task_200804101742_0001_m_032077_2,396) failed :
> 2008-04-21 02:42:49,468 WARN org.apache.hadoop.mapred.TaskTracker:
> getMapOutput(task_200804101742_0001_m_032077_2,396) failed :
> 2008-04-21 02:43:03,717 WARN org.apache.hadoop.mapred.TaskTracker:
> getMapOutput(task_200804101742_0001_m_032077_2,396) failed :
> Shouldn't the task tracker failed early without trying so many times?
