Quickstart: Create Interactive Query cluster in Azure HDInsight using ARM template
In this quickstart, you use an Azure Resource Manager template (ARM template) to create an Interactive Query cluster in Azure HDInsight. Interactive Query (also called Apache Hive LLAP, or Low Latency Analytical Processing) is an Azure HDInsight cluster type.
An Azure Resource Manager template is a JavaScript Object Notation (JSON) file that defines the infrastructure and configuration for your project. The template uses declarative syntax. You describe your intended deployment without writing the sequence of programming commands to create the deployment.
If your environment meets the prerequisites and you're familiar with using ARM templates, select the Deploy to Azure button. The template will open in the Azure portal.
Prerequisites
If you don't have an Azure subscription, create a free account before you begin.
Review the template
The template used in this quickstart is from Azure Quickstart Templates.

Two Azure resources are defined in the template:
- Microsoft.Storage/storageAccounts: create an Azure Storage Account.
- Microsoft.HDInsight/cluster: create an HDInsight cluster.
Deploy the template
Select the Deploy to Azure button below to sign in to Azure and open the ARM template.
Enter or select the following values:
Property Description Subscription From the drop-down list, select the Azure subscription that's used for the cluster. Resource group From the drop-down list, select your existing resource group, or select Create new. Location The value will autopopulate with the location used for the resource group. Cluster Name Enter a globally unique name. For this template, use only lowercase letters, and numbers. Cluster Login User Name Provide the username, default is admin.Cluster Login Password Provide a password. The password must be at least 10 characters in length and must contain at least one digit, one uppercase, and one lower case letter, one non-alphanumeric character (except characters ' ` ").Ssh User Name Provide the username, default is sshuser Ssh Password Provide the password. 
Review the TERMS AND CONDITIONS. Then select I agree to the terms and conditions stated above, then Purchase. You'll receive a notification that your deployment is in progress. It takes about 20 minutes to create a cluster.
Review deployed resources
Once the cluster is created, you'll receive a Deployment succeeded notification with a Go to resource link. Your Resource group page will list your new HDInsight cluster and the default storage associated with the cluster. Each cluster has an Azure Blob Storage account, or an Azure Data Lake Storage Gen2 dependency. It's referred as the default storage account. The HDInsight cluster and its default storage account must be colocated in the same Azure region. Deleting clusters doesn't delete the storage account.
Clean up resources
After you complete the quickstart, you may want to delete the cluster. With HDInsight, your data is stored in Azure Storage, so you can safely delete a cluster when it isn't in use. You're also charged for an HDInsight cluster, even when it isn't in use. Since the charges for the cluster are many times more than the charges for storage, it makes economic sense to delete clusters when they aren't in use.
From the Azure portal, navigate to your cluster, and select Delete.
You can also select the resource group name to open the resource group page, and then select Delete resource group. By deleting the resource group, you delete both the HDInsight cluster, and the default storage account.
