> This proposal talks about the issues of YARN fair scheduling policy, and 
> tries to solve them by YARN-3806 and the new scheduling policy called time 
> based fair scheduling.
> Time based fair scheduling policy is proposed to enforces time based fairness 
> among users. For example, if two users share the cluster weekly, each user’s 
> fair share is half of the cluster per week. At a particular week, if the 
> first user has used the whole cluster for first half of the week, then in 
> second half of the week, second user will always have priority to use cluster 
> resources since the first user has used up its fair share of the cluster 
> already.
