Chia-Ping Tsai commented on YUNIKORN-1728: ------------------------------------------ {quote} Personally, I think percentage-based quotas are a terrible hack (that was unfortunately required in the early YARN days). At best, we could possibly support them if and only if the parent queue capacities are static. {quote} 100% agree that. We has a similar discussion recently. If the max resources (yk quota) can be percentage-based, it means the autoscaler can increase the quota when adding/scaling nodes (assume it is based on root max resources) . It results in more apps can fit into the queues due to larger quota... so the "quota" will lose its job :smile > MaxApplication enforcement supports percentage of resources > ----------------------------------------------------------- > > Key: YUNIKORN-1728 > URL: https://issues.apache.org/jira/browse/YUNIKORN-1728 > Project: Apache YuniKorn > Issue Type: New Feature > Components: core - scheduler > Reporter: Rainie Li > Assignee: Rainie Li > Priority: Major > > Currently we need to set queue with guaranteed resources. > example: > {code:java} > queues: > - name: root > submitacl: '*' > queues: > - name: queue1 > submitacl: '*' > maxapplications: 12 > resources: > guaranteed: > {memory: 6290G, vcore: 816} > max: > {memory: 31450G, vcore: 4080} > {code} > It will be convenient to support percentage, so that we can configure queue > without calculating the actual number. > {code:java} > queues: > - name: root > submitacl: '*' > queues: > - name: queue1 > submitacl: '*' > maxapplications: 12 > resources: > guaranteed: > {memory: 20%, vcore: 20%} > max: > {memory: 31450G, vcore: 4080} > {code} -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@yunikorn.apache.org For additional commands, e-mail: issues-h...@yunikorn.apache.org
