Allen Wittenauer updated MAPREDUCE-4085:
----------------------------------------
Attachment: MAPREDUCE-4085-branch-1.0.4.txt
Here's an updated version for anyone who wants it. This one also includes the
ability for users to set a smaller task time limit
(mapred.job.{map|reduce}.task-wallclock-limit) in case they want something
faster. i.e., "I know my task should finish in 5 minutes, so kill it if it
doesn't". Of course, the queue time out will still kick in if the user
provided time is longer.
> Kill task attempts longer than a configured queue max time

> For some environments, it is desirable to have certain queues have an SLA
> with regards to task turnover. (i.e., a slot will be free in X minutes and
> scheduled to the appropriate job) Queues should have a 'task time limit'
> that would cause task attempts over this time to be killed. This leaves open
> the possibility that if the task was on a bad node, it could still be
> rescheduled up to max.task.attempt times.
