Windows DSN Configuration

Using the Microsoft ODBC Data Source Administrator

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the DSN is created during the installation process.

Complete the following steps to edit the DSN configuration:

Select Start > Search, and enter ODBC Data Sources in the Search box.
Choose the version of the ODBC Administrator that corresponds to the bitness of your application (32-bit or 64-bit).
Click the System DSN tab.
Select the system data source and click Configure.
Edit the information on the Connection tab and click OK.

Note: For .NET Framework 4.0, the driver distributes Microsoft Visual C++ 2015-2022 Redistributable. For .NET Framework 3.5, the driver distributes Microsoft Visual C++ 2008 Redistributable.

Connecting to HDFS

In order to connect, set the following connection properties:

Host: Set this value to the host of your HDFS installation.
Port: Set this value to the port of your HDFS installation. Default port: 50070
UseSSL: (Optional) Set this value to 'True', to negotiate TLS/SSL connections to the HDFS server. Default: 'False'.

Authenticating to HDFS

There are two authentication methods available for connecting to the HDFS data source, Anonymous Authentication and Negotiate (Kerberos) Authentication.

Anonymous Authentication

In some situations, HDFS may be connected to without any authentication connection properties. To do so, set the AuthScheme to None (default).
