Elek, Marton updated HDDS-1871:
-------------------------------
Priority: Blocker (was: Major)
> Remove anti-affinity rules from k8s minkube example
> ---------------------------------------------------
>
> Key: HDDS-1871
> URL: https://issues.apache.org/jira/browse/HDDS-1871
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: kubernetes
> Reporter: Elek, Marton
> Assignee: Elek, Marton
> Priority: Blocker
>
> HDDS-1646 introduced real persistence for k8s example deployment files which
> means that we need anti-affinity scheduling rules: Even if we use statefulset
> instead of daemonset we would like to start one datanode per real nodes.
> With minikube we have only one node therefore the scheduling rule should be
> removed to enable at least 3 datanodes on the same physical nodes.
> How to test:
> {code}
> mvn clean install -DskipTests -f pom.ozone.xml
> cd hadoop-ozone/dist/target/ozone-0.5.0-SNAPSHOT/kubernetes/examples/minikube
> minikube start
> kubectl apply -f .
> kc get pod
> {code}
> You should see 3 datanode instances.
