Qiheng He commented on HIVE-28453:
----------------------------------

To be honest, I've spent the past month trying to find some original 
documentation on how this feature was designed, but I'm having a hard time 
matching the unit tests for JWT and SAML to those docs. I'm afraid I can't help.

> The optional values ​​for `hive.server2.authentication` seem to be missing 
> `JWT` and `SAML`?

> - The optional values ​​for *hive.server2.authentication* seem to be missing 
> *JWT* and {*}SAML{*}?
>  - 
> [https://cwiki.apache.org/confluence/display/Hive/Setting+Up+HiveServer2#SettingUpHiveServer2-Authentication/SecurityConfiguration]
>  mentions that there are only 6 optional values ​​for 
> *hive.server2.authentication* .
> {code:none}
> Authentication mode:
> hive.server2.authentication – Authentication mode, default NONE. Options are 
> NONE (uses plain SASL), NOSASL, KERBEROS, LDAP, PAM and CUSTOM.
> {code}
>  - I looked at 
> [https://github.com/apache/hive/blob/rel/release-4.0.0/service/src/java/org/apache/hive/service/auth/HiveAuthConstants.java]
>  and it seems there are 2 additional authentication methods, namely *SAML* 
> and {*}JWT{*}.
> {code:java}
> public enum AuthTypes {
>     NOSASL("NOSASL"),
>     NONE("NONE"),
>     LDAP("LDAP"),
>     KERBEROS("KERBEROS"),
>     CUSTOM("CUSTOM"),
>     PAM("PAM"),
>     SAML("SAML"),
>     JWT("JWT");
>     private final String authType;
>     AuthTypes(String authType) {
>       this.authType = authType;
>     }
>     public String getAuthName() {
>       return authType;
>     }
>   }
> {code}
>  - I can hardly find any configuration instructions for *JWT* and *SAML* in 
> the documentation. Is there any known Jira issue?
