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
