Remarks
This property controls what authentication mechanism the component should use when connecting to the server.
Possible values are:
| 0 (amNone - default) | No authentication is performed. |
| 1 (amSimple) | Hadoop pseudo/simple authentication is performed. |
| 2 (amBasic) | Basic authentication is performed. |
| 3 (amNTLM) | NTLM authentication is performed. |
| 4 (amNegotiate) | Negotiate authentication is performed. |
| 5 (amOAuth) | OAuth authentication is performed. |
When set to 1 (amSimple), the value of the User property is automatically sent in every request using the user.name query parameter.
When set to 2 (amBasic), 3 (amNTLM), or 4 (amNegotiate), the values held by the User and Password properties will be used to perform Basic, NTLM, or Negotiate (e.g., Kerberos SPNEGO) authentication.
When set to 5 (amOAuth), the value of the Authorization property is automatically sent in every request using the Authorization HTTP header.
