Creating the Data Source Name

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

Editing the DSN Configuration

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the DSN is created during the installation process, as described in Installing the Connector.

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. Click the System DSN tab.
  4. Select the system data source and click Configure.
  5. Edit the information on the Connection tab and click OK.

Connecting to Apache Impala

In order to connect to Apache Impala, set the Server, Port, and ProtocolVersion. You may optionally specify a default Database.

Authenticating to Apache Impala

There are several ways to authenticate to Apache Impala including NOSASL,LDAP,KERBEROS. The following sections cover how to connect over each.

Authenticating with NOSASL

When using NOSASL, no authentication is performaned. It is used when you are connecting to a server from a trusted location such as a test machine on your local network. By default, NOSASL is as the default AuthScheme, so no additional connection properties need to be set.

Authenticating with LDAP

To authenticate with LDAP, set the following connection properties:

  • AuthScheme: Set this to LDAP.
  • User: Set this to user to login as.
  • Password: Set this to the password of the user.
To authenticate, set User, Password, and AuthScheme.

Authenticating with Kerberos

Please see Using Kerberos for details on how to authenticate with Kerberos.
