> Key: YUNIKORN-2664
> URL: https://issues.apache.org/jira/browse/YUNIKORN-2664
> Project: Apache YuniKorn
> Issue Type: Wish
> Components: shim - kubernetes
> Reporter: Volodymyr Kot
> Priority: Major
>
> Hey, I noticed that by default YuniKorn is run as a Deployment with a single
> replica:
> [https://github.com/apache/yunikorn-release/blob/aa9a2939eed81fc74fbbf7afbc0fe60c5aa0acd0/helm-charts/yunikorn/templates/deployment.yaml#L31]
> and leader election is disabled in scheduler configuration:
> [https://github.com/apache/yunikorn-k8shim/blob/36111c41d97658e168e640c284fe8d71921883b4/conf/scheduler-config.yaml#L20]
>
> Is there anything about the architecture of YuniKorn that makes this
> hard/impossible to do? Or would you be open to a PR that adds ability to run
> with multiple replicas and leader election?
