Quick Start

In this quick start, we will use Kubedoop's hive-operator as an example to show how to deploy a Hive Metastore in a Kubernetes cluster.

Prerequisites​

To start using Kubedoop, you need to meet the following requirements:

  • Install kubectl
  • Install Helm v3+
  • Prepare a Kubernetes cluster

Install the Operator​

Kubedoop uses Helm charts to deploy and manage Operators. Container images are published to quay.io and charts are distributed via a Helm repository.

Add the Helm Repository​

helm repo add kubedoop https://zncdatadev.github.io/kubedoop-helm-charts/
helm repo update

Install Built-in Operators​

The commons-operator, listener-operator, and secret-operator are required dependencies for all product Operators. Install them first:

helm install commons-operator kubedoop/commons-operator -n operators --create-namespace
helm install listener-operator kubedoop/listener-operator -n operators
helm install secret-operator kubedoop/secret-operator -n operators

Install the Hive Operator​

helm install hive-operator kubedoop/hive-operator -n operators

Verify that the Operator pod is running normally:

kubectl get pods -n operators

Create Namespace​

Create a namespace for Hive to deploy the Hive cluster:

kubectl create ns hive

Deploy a Hive Cluster​

The Hive cluster is managed by the hive-operator. You can deploy a Hive Metastore by creating a HiveMetastore custom resource:

kubectl apply -f - <<EOF
apiVersion: hive.kubedoop.dev/v1alpha1
kind: HiveMetastore
metadata:
  name: hive-metastore
  namespace: hive
spec:
  roleGroups:
    default:
      replicas: 1
EOF

Access Hive Metastore​

After the Hive cluster is deployed, you can access the Hive Metastore with the following command:

kubectl exec -it hive-metastore-0 -n hive -- bash

Clean Up Resources​

Run the following command to clean up the Hive cluster:

kubectl delete hivemetastore hive-metastore -n hive

Run the following command to uninstall the Operators:

helm uninstall hive-operator -n operators
helm uninstall secret-operator -n operators
helm uninstall listener-operator -n operators
helm uninstall commons-operator -n operators
