Apache YuniKorn

YuniKorn YuniKorn is a light-weight, universal resource scheduler for container orchestrator systems.

Apache YuniKorn (Incubating) is a new Apache incubator project that offers rich scheduling capabilities on Kubernetes. It fills the scheduling gap while running Big Data workloads on Kubernetes, with a ton of useful features such as hierarchical queues, elastic queue quotas, resource fairness, and job ordering

You can define batchScheduler: "yunikorn" when you are running Spark Applications using SparkK8sOperator


This step deploys the Apache YuniKorn K8s schedular with default Helm Chart config

  enable_yunikorn = true

Alternatively, you can override the helm values by using the code snippet below

  enable_yunikorn = true

  yunikorn_helm_config = {
    name       = "yunikorn"                                 # (Required) Release name.
    repository = "" # (Optional) Repository URL where to locate the requested chart.
    chart      = "yunikorn"                                 # (Required) Chart name to be installed.
    version    = "0.12.2"                               # (Optional) Specify the exact chart version to install. If this is not specified, it defaults to the version set within default_helm_config:
    values     = [templatefile("${path.module}/values.yaml", {})]
