             Summary: Proposal of Time Based Fair Scheduling for YARN
                 Key: YARN-3808
                 URL: https://issues.apache.org/jira/browse/YARN-3808
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: fairscheduler, scheduler
            Reporter: Wei Shao

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 

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.
