Quickstart: Create an HDInsight on AKS cluster pool using Azure CLI

  • Article

Note

We will retire Azure HDInsight on AKS on January 31, 2025. Before January 31, 2025, you will need to migrate your workloads to Microsoft Fabric or an equivalent Azure product to avoid abrupt termination of your workloads. The remaining clusters on your subscription will be stopped and removed from the host.

Only basic support will be available until the retirement date.

Important

This feature is currently in preview. The Supplemental Terms of Use for Microsoft Azure Previews include more legal terms that apply to Azure features that are in beta, in preview, or otherwise not yet released into general availability. For information about this specific preview, see Azure HDInsight on AKS preview information. For questions or feature suggestions, please submit a request on AskHDInsight with the details and follow us for more updates on Azure HDInsight Community.

HDInsight on AKS introduces the concept of cluster pools and clusters, which allow you to realize the complete value of data lakehouse.

  • Cluster pools are a logical grouping of clusters and maintain a set of clusters in the same pool, which helps in building robust interoperability across multiple cluster types. It can be created within an existing virtual network or outside a virtual network.

    A cluster pool in HDInsight on AKS corresponds to one cluster in AKS infrastructure.

  • Clusters are individual compute workloads, such as Apache Spark, Apache Flink, or Trino, which can be created in the same cluster pool.

For every cluster type, you must have a cluster pool. It can be created independently or you can create new cluster pool during cluster creation. In this quickstart, you learn how to create a cluster pool using the Azure CLI.

Prerequisites

Ensure that you completed the subscription prerequisites before creating a cluster pool.

Launch Azure Cloud Shell

The Azure Cloud Shell is an interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.

Define environment variables

The first step is to define the environment variables. Environment variables are commonly used in Linux to centralize configuration data to improve consistency and maintainability of the system. Create the following environment variables to specify the names of resources that you create later in this tutorial:

export ResourceGroup="HDIonAKSCLI"
export Region=EastUS
export HDIonAKSClusterPoolName="contosopool"
export NodeType="Standard_E4s_v3"
export ClusterVersion="1.1"

Log in to Azure using the CLI

In order to run commands in Azure using the CLI, you need to log in first. Log in using the az login command.

Create a resource group

A resource group is a container for related resources. All resources must be placed in a resource group. The az group create command creates a resource group with the previously defined $ResourceGroup and $Region parameters.

az group create --name $ResourceGroup --location $Region

Output:

{
  "id": "/subscriptions/aaaa0a0a-bb1b-cc2c-dd3d-eeeeee4e4e4e/resourceGroups/HDIonAKSCLI",
  "location": "eastus",
  "managedBy": null,
  "name": "HDIonAKSCLI",
  "properties": {
    "provisioningState": "Succeeded"
  },
  "tags": null,
  "type": "Microsoft.Resources/resourceGroups"
}

Create the HDInsight on AKS cluster pool

To create a HDInsight on AKS cluster pool in this resource group, use the az hdinsight-on-aks clusterpool create command:

az hdinsight-on-aks clusterpool create --cluster-pool-name
                                       --resource-group
                                       [--api-server-authorized-ip-ranges]
                                       [--cluster-pool-version]
                                       [--enable-log-analytics {0, 1, f, false, n, no, t, true, y, yes}]
                                       [--la-workspace-id]
                                       [--location]
                                       [--managed-rg-name]
                                       [--no-wait {0, 1, f, false, n, no, t, true, y, yes}]
                                       [--outbound-type {loadBalancer, userDefinedRouting}]
                                       [--private-server-enabled {0, 1, f, false, n, no, t, true, y, yes}]
                                       [--subnet-id]
                                       [--tags]
                                       [--workernode-size]

Here's an example:

az hdinsight-on-aks clusterpool create --resource-group $ResourceGroup --cluster-pool-name $HDIonAKSClusterPoolName --location $Region --workernode-size $NodeType --cluster-pool-version $ClusterVersion

It takes a few minutes to create the HDInsight on AKS cluster pool. The following example output shows the created operation was successful.

Output:

Note

For more information about cluster pool CLI commands, see commands.

Clean up resources

When no longer needed, clean up unnecessary resources to avoid Azure charges. You can remove the resource group, cluster pool, and all other resources in the resource group using the az group delete command.

Note

To delete a cluster pool, ensure there are no active clusters in the cluster pool.
