-# Create Apache Hadoop cluster with secure transfer storage accounts in Azure HDInsight
+# Apache Hadoop clusters with secure transfer storage accounts in Azure HDInsight
 
 The [Secure transfer required](../storage/common/storage-require-secure-transfer.md) feature enhances the security of your Azure Storage account by enforcing all requests to your account through a secure connection. This feature and the wasbs scheme are only supported by HDInsight cluster version 3.6 or newer.
 
-**Enabling secure storage transfer after creating a cluster can result in errors using your storage account and is not recommended. It is better to create a new cluster with the property enabled.**
+> [!IMPORTANT]
+> Enabling secure storage transfer after creating a cluster can result in errors using your storage account and is not recommended. It is better to create a new cluster using a storage account with secure transfer already enabled.
 
-## Prerequisites
+## Storage accounts
 
-Before you begin this article, you must have:
+### Azure portal
 
-* Azure subscription: To create a free one-month trial account, browse to [azure.microsoft.com/free](https://azure.microsoft.com/free).
-* An Azure Storage account with secure transfer enabled. For the instructions, see [Create a storage account](../storage/common/storage-account-create.md) and [Require secure transfer](../storage/common/storage-require-secure-transfer.md). 
-* A Blob container on the storage account.
+By default, the secure transfer required property is enabled when you create a storage account in Azure portal.
 
-## Create cluster
+To update an existing storage account with Azure portal, see [Require secure transfer with Azure portal](../storage/common/storage-require-secure-transfer.md#require-secure-transfer-for-an-existing-storage-account).
 
-[!INCLUDE [delete-cluster-warning](../../includes/hdinsight-delete-cluster-warning.md)]
+### PowerShell
 
-In this section, you create a Hadoop cluster in HDInsight using an [Azure Resource Manager template](../azure-resource-manager/templates/deploy-powershell.md). The template is located in [GitHub](https://azure.microsoft.com/resources/templates/101-hdinsight-linux-with-existing-default-storage-account/). Resource Manager template experience isn't required for following this article. For other cluster creation methods and understanding the properties used in this article, see [Create HDInsight clusters](hdinsight-hadoop-provision-linux-clusters.md).
+For the PowerShell cmdlet [New-AzStorageAccount](https://docs.microsoft.com/powershell/module/az.storage/new-azstorageaccount), ensure parameter `-EnableHttpsTrafficOnly` is set to `1`.
 
-1. Click the following image to sign in to Azure and open the Resource Manager template in the Azure portal.
+To update an existing storage account with PowerShell, see [Require secure transfer with PowerShell](../storage/common/storage-require-secure-transfer.md#require-secure-transfer-with-powershell).

+### Azure CLI
 
-2. Follow the instructions to create the cluster with the following specifications:
+For the Azure CLI command [az storage account create](https://docs.microsoft.com/cli/azure/storage/account?view=azure-cli-latest#az-storage-account-create), ensure parameter `--https-only` is set to `true`.
 
-    * Specify HDInsight version 3.6. Version 3.6 or newer is required.
-    * Specify a secure transfer enabled storage account.
-    * Use short name for the storage account.
-    * Both the storage account and the blob container must be created beforehand.
-
-      For the instructions, see [Create cluster](hadoop/apache-hadoop-linux-tutorial-get-started.md#create-cluster).
-
-If you use script action to provide your own configuration files, you must use wasbs in the following settings:
-
-* fs.defaultFS (core-site)
-* spark.eventLog.dir
-* spark.history.fs.logDirectory
+To update an existing storage account with Azure CLI, see [Require secure transfer with Azure CLI](../storage/common/storage-require-secure-transfer.md#require-secure-transfer-with-azure-cli).
