> 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
> extended fair scheduling.
> Time extended fair scheduling policy is proposed to enforces fairness over
> time 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 time extended fair share of
> the cluster already.
