Before You Begin

ADLSv2 Private Link: If you require a private link to ADLSv2, see Configuring an ADLSv2 Private Link.

Enable Hierarchical Namespace: Verify the storage account has hierarchical namespace enabled on it. This is required. To confirm, go to your storage account in the Azure portal and select Overview > Properties > Data Lake Storage. Make sure to enable Hierarchical namespace.

Store Account Key: If you plan to use a storage account key to set up an Azure Data Lake Storage (ADLSv2) connection, you need to also find your access keys in the Azure portal.

2. Go to Security + networking > Access keys.
3. Choose Show keys to view your access keys and connection strings.
4. Copy these keys to your clipboard or a text file. You will need this later.
