Any mechanism in Hadoop to run in background
Hi, All...
We have a user case intended to run Mapreduce in background, while the
server serves online operations. The MapReduce job may have lower priority
comparing to the online jobs..

I know this is a different use case of Mapreduce comparing to its
originally targeted scenario (where Mapreduce largely own resource
exclusively)... But I want to know if there is any tuning knobs that allow
Mapreduce to run in low priority/with limited resource.

Thanks,
Yun
