Remarks

This field is used to authenticate against the server. Use the following options to select your authentication scheme:

• None: Set this to use anonymous authentication and connect to the HDFS data source without specifying the user credentials.
• Negotiate: If AuthScheme is set to Negotiate, the driver will negotiate an authentication mechanism with the server. Set AuthScheme to Negotiate if you want to use Kerberos authentication.
• Token: Set this to authenticate using an AccessToken.
