Bowen Li created YUNIKORN-614: --------------------------------- Summary: support co-deployment of YuniKorn with other schedulers, or multiple YuniKorn, in a single cluster Key: YUNIKORN-614 URL: https://issues.apache.org/jira/browse/YUNIKORN-614 Project: Apache YuniKorn Issue Type: New Feature Components: core - scheduler, deployment Reporter: Bowen Li
IIUIC, YuniKorn right now cannot be co-deployed with other schedulers, like default K8S scheduler, nor can users deploy multiple YuniKorn, in a single cluster. We have use cases of such requirements: # we want to have YuniKorn as the "active" scheduler to take job requests, and still be able to route requests to another scheduler as "backup" in case of any issues. # deploy and test a new YuniKorn version to take like 20% traffic to a K8S cluster, while keeping an old, stable version taking the remaining 80% traffic Seems we cannot do either at the moment, and a workaround is to deploy another cluster for the above use cases, which inevitably bring in huge DevOps costs. Ideally, we should support co-deployment of YuniKorn with other schedulers, or multiple YuniKorn, in a single cluster. Traffic routing can be scoped and determined by some K8S native concepts like namespaces and node groups, or some custom concepts of YuniKorn which can be mapped to K8S native concepts for easier management -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@yunikorn.apache.org For additional commands, e-mail: dev-h...@yunikorn.apache.org
