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
  • Prepare a Kubernetes cluster

Install OLM​

Kubedoop relies on the Operator Lifecycle Manager (OLM) to manage Operators. If OLM is not installed in your cluster, you can install it with the following command:

curl -sL https://github.com/operator-framework/operator-lifecycle-manager/releases/download/v0.25.0/install.sh | bash -s v0.25.0

Install hive-operator​

OLM manages the installation of Operators through Subscription. We can install the hive-metastore-operator by creating a Subscription:

kubectl apply -f https://raw.githubusercontent.com/kubedoop.dev/kubedatastack/main/examples/hive/olm-subscriptions.yaml

Verify that the operator's pod is running normally:

kubectl get pods -n operator

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. We can deploy a Hive Metastore by creating a HiveCluster object:

kubectl apply -f https://raw.githubusercontent.com/kubedoop.dev/kubedatastack/main/examples/hive/hive-metastore.yaml

Access Hive Metastore​

After the Hive cluster is deployed, we 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 -f https://raw.githubusercontent.com/kubedoop.dev/kubedatastack/main/examples/hive/hive-cluster.yaml

Run the following command to clean up the operator:

kubectl delete -f https://raw.githubusercontent.com/kubedoop.dev/kubedatastack/main/examples/hive/olm-subscriptions.yaml
