本文探讨了公平调度器的工作原理及其在资源分配中的应用。通过案例分析，讨论了当两个顺序任务使用公平调度器时可能产生的结果及影响，并考虑了如何避免无限循环等问题。
as i reviewed the book,it saied:
a.it 's goal is to let each user fairly 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 SEQUENCE jobs,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".
