Configure Azure

Create registered application

You must create an Azure Active Directory (AAD) application and grant it the desired access permissions, such as read/write access to the ADLS resource and read/write access to the Azure Key Vault secrets.

Info

NOTE: If you are integrating with Azure Databricks and are Managed Identities for authentication, please skip this section. That configuration is covered in a later step.

This service principal is used by the

D s platform
for access to all Azure resources. For more information, see https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-create-service-principal-portal.

After you have registered, acquire the following information:

Azure PropertyLocationUse
Application ID

Acquire this value from the Registered app blade of the Azure Portal.

Applied to

D s platform
configuration: azure.applicationid.

Service User Key

Create a key for the Registered app in the Azure Portal.

Applied to

D s platform
 configuration: azure.secret.

Info

NOTE: If you are using Azure AD to integrate with an Azure Databricks cluster, the Azure AD secret value stored in azure.secret must begin with an alphanumeric character. This is a known issue.


Directory IDCopy the Directory ID from the Properties blade of Azure Active Directory.

Applied to

D s platform
 configuration: azure.directoryId.

Excerpt Include
Azure Install Create Registered Application
Azure Install Create Registered Application
nopaneltrue

These properties are applied later in the configuration process.

Configure the Platform

Configure for HDI

If you are integrating the

D s platform
with a pre-existing HDI cluster, additional configuration is required. See Configure for HDInsight.

Info

NOTE: If you created a new HDI cluster as part of the installation, all required is listed below.

Configure for Azure Databricks

You can integrate the

D s platform
with Azure Databricks. For more information, see Configure for Azure Databricks.

Configure base storage layer

For Azure installations, you can set your base storage layer to be HDFS or WASB.

Info

NOTE: The base storage layer must be set after installation. After it has been configured, it cannot be modified.

See Set Base Storage Layer.

Configure for Key Vault

For authentication purposes, the 

D s platform
 must be integrated with an Azure Key Vault keystore. See Configure Azure Key Vault.

Configure for SSO

If needed, you can integrate the

D s platform
with Azure AD for Single-Sign On to the platform. See Configure SSO for Azure AD.

Configure for ADLS Gen2

Enable read-only or read-write access to ADLS Gen2. For more information, see Enable ADLS Gen2 Access.

Configure for ADLS Gen1

Enable read-only or read-write access to ADLS Gen1. For more information, see Enable ADLS Access.

Configure for WASB

Enable read-only or read-write access to WASB. For more information on integrating with WASB, see Enable WASB Access.

Configure relational connections

If you are integrating

D s product
with relational datastores, please complete the following configuration sections.

Create encryption key file

An encryption key file must be created on the

D s node
. This key file is shared across all relational connections. See Create Encryption Key File.

Create Hive connection

You can create a connection to the Hive instance on the HDI cluster with some modifications.

  • High Availability: Natively, Azure supports high availability for HiveServer2 via Zookeeper. Host and port information in the JDBC URL must be replaced with a Zookeeper quorum.

In addition to the other Hive connection properties, please specify the following values for the properties listed below:

PropertyDescription
Host

Use your Zookeeper quorum value. For the final node of the list, omit the port number. Example:

Code Block
zk1.cloudapp.net:2181,zk2.cloudapp.net:2181,zk3.cloudapp.net


PortSet this value to 2181.
Connect String options

In addition to any options required for your environment, include the following option:

Code Block
/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2


DatabaseEnter your Hive database name.

Connections are created through the Connections page. See Connections Page.

For additional details on creating a connection to Hive, see Create Hive Connections.

A Hive connection can also be created using the above property substitutions via programmatic methods.

Create Azure SQL Database connection
