Components: mapred
Affects Versions: 0.13.1
Reporter: Koji Noguchi

One task wasn't killed when its job was killed.
On the TaskTracker log, it showed,
2007-08-21 17:02:29,219 INFO org.apache.hadoop.mapred.TaskTracker:
LaunchTaskAction: task_0133_r_000080_2 <**************

[task_0133_r_000080_2 continue to run]
Of course the JobTracker kept on complaining
2007-08-22 19:06:37,880 INFO org.apache.hadoop.mapred.JobTracker: Serious
problem. While updating status, cannot find taskid task_0133_r_000080_2
