Subject question on yarn and fairscheduler
Date Tue, 20 May 2014 06:53:43 GMT
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.
