FairScheduler in hadoop mapreduce
as i reviewed the book,it saied:a.it 's goal is to let each userfairly share the cluster resources
b.jobs are placed in pools,and each user has their own pool.
c.u can set the priorify of a pool ,so
d.this Scheduler supports preemption
first ,i thought,if i run a client to submit two SEQUENCEjobs,if i use FAIR sheduler,
1.whether the results will be out of order as the jobs are Faired?
2.sinc they are faired,so whether it wil be lead to definite-loop as it faire resources fluently?(for example,one of our national policys is "一部分人先富起来,最終实现共同富裕".
