[jira] [Created] (MAPREDUCE-4085) Kill task attempts longer than a configured queue max time

Kill task attempts longer than a configured queue max time
----------------------------------------------------------

                 Key: MAPREDUCE-4085
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4085
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: task
            Reporter: Allen Wittenauer


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.
