Hi some questions on yarn+fairscheduler: 1. is the maxMaps and maxReduces in allocations.xml actually work? notice it is not working in my setup. 2. my job always fail with diagnostics such as: Task task_1400033851458_4824_m_000006 failed 4 times . is it possible that this is due to preempted too many times? or any other issue. At the same job, there are also tasks get killed with note: Attmpt state missing from History : marked as KILLED
any help would be appreciated. Thanks.
