             Summary: Cluster capacity in SchedulingPolicy is updated only on 
allocation file reload
                 Key: YARN-6194
                 URL: https://issues.apache.org/jira/browse/YARN-6194
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: fairscheduler
    Affects Versions: 2.8.0
            Reporter: Karthik Kambatla
            Assignee: Yufei Gu


Some of the {{SchedulingPolicy}} methods need cluster capacity which is set 
using {{#initialize}} today. However, {{initialize()}} is called only on 
allocation reload. If nodes are added between reloads, the cluster capacity is 
not considered until the next reload.
