Karthik Kambatla commented on YARN-1959: ---------------------------------------- Approach looks good. Couple of comments: # Can we add a single method to SchedulingPolicy that takes "available" cluster resources, queue's fairshare and current usage? May be, we can call that method computeHeadroom? # The amount of resources available in the cluster can be looked up in FairScheduler.rootMetrics. > Fix headroom calculation in Fair Scheduler > ------------------------------------------ > > Key: YARN-1959 > URL: https://issues.apache.org/jira/browse/YARN-1959 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Sandy Ryza > Assignee: Anubhav Dhoot > Attachments: YARN-1959.prelim.patch > > > The Fair Scheduler currently always sets the headroom to 0. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
