Amareshwari Sriramadasu updated HADOOP-3150:
--------------------------------------------
Attachment: patch-3150.txt
Here is patch doing :
1. incorporates Owen's comments.
2. CleanupTask can be reduce or map task. But the job has two clenaup tips one
for map, one for reduce. When a task tracker asks for a task with map slot,
cleanup mapTip starts an attempt and vice versa. When the one of the cleanup
tips is successful, the job will kill the other tip. Thoughts?
3. Earlier patch was not scheduling cleanup task in proper slot, this patch
fixes it.
4. Also Fixes a bug in JobInProgress.updateTaskStatus()
5. Removes a redudant log message.
> Move task file promotion into the task
