 # Create Apache Hadoop cluster 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.
