             Summary: Running YuniKorn as leader-elected controller with multiple replicas
                 Key: YUNIKORN-2664
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-2664
             Project: Apache YuniKorn
          Issue Type: Wish
          Components: shim - kubernetes
            Reporter: Volodymyr Kot


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?
