---------------------------------------
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?
