Valid Values
0 | 1 | -1
Behavior
If set to 0 (User ID/Password), the driver sends the user ID in clear text and an encrypted password to the server for authentication.
If set to 1 (Kerberos Authentication), the driver uses Kerberos authentication. This method supports both Windows Active Directory Kerberos and MIT Kerberos environments.
Note: This setting is supported only for HiveServer2 connections.
If set to -1 (No Authentication), the driver sends the user ID and password in clear text to the server for authentication.
