This section describes how to edit the DSN configuration and then authenticate and connect to Apache Phoenix APIs.

DSN Configuration

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the installation process creates a both a user DSN and a system DSN, as described in Installing the Connector.

Note: The connector stores connection information in the Windows registry. To ensure that the connector can write to the registry, either run Power BI as an administrator or use a User DSN for your connection instead of a System DSN.

User DSN

Complete the following steps to edit the DSN configuration:

1. Select Start > Search, and enter ODBC Data Sources in the Search box.
2. Choose the version of the ODBC Administrator that corresponds to the bitness of your Power BI Desktop installation (32-bit or 64-bit).
3. Select the system data source and click Configure.
4. Edit the information on the Connection tab and click OK.

System DSN

Configure the system DSN the same way as the user DSN, except you will need to switch to the System DSN tab before performing Step 3.

Connecting to Apache Phoenix

The CData Power BI Connector for Apache Phoenix connects to Apache Phoenix via the Phoenix Query Server. Set the URL connection property to connect to Apache Phoenix.

The URL property will typically be the host name or IP address of the server hosting Apache Phoenix followed by the port, for example: http://localhost:8765.

Authenticating to Apache Phoenix

By default, no authentication will be used (plain). If authentication is configured for your server, you can configure one of the following authentication methods.

Basic

If your instance of Apache Phoenix has set up the basic authentication layer, set the following to authenticate:

• AuthScheme: Set this to Basic.
• User: Set this to the user of your Apache Phoenix instance.
• Password: Set this to the password of your Apache Phoenix instance.

Azure HDInsight

To authenticate to Azure HDInsight, set the following:

• AuthScheme: Set this to AzureHDInsight.
• User: Set this to the cluster username that you specified when creating the cluster on Azure HDInsight.
• Password: Set this to the cluster password that you specified when creating the cluster on Azure HDInsight.
• ClusterName: Set this to the name of the cluster containing your Azure HDInsight instance.

All calls are sent to a gateway which picks one of the nodes to handle the request. Accessing the specific nodes is possible if you are running within the internal virtual network of the cluster.

Kerberos

Set the AuthScheme to Negotiate. See Using Kerberos for details on how to authenticate with Kerberos.
