----------------------------------
Summary: 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
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.
