--------------------------------------

[~dapengsun] [~Ferd] 
I am wondering if the api HiveAuthorizationTranslator, should have methods that 
operate on a single element instead of a list of them. That seems more generic 
and captures the basic logic - 
ie instead of -
{code} public List<HivePrincipal> getHivePrincipals(List<PrincipalDesc> 
principals)  {code}
have - 

{code} public HivePrincipal getHivePrincipals(PrincipalDesc principals) {code}
What are your thoughts ?


> Remove exposure to internal privilege and principal classes in HiveAuthorizer

> The changes in HIVE-11179 expose several internal classes to 
> HiveAuthorization implementations. These include PrivilegeObjectDesc, 
> PrivilegeDesc, PrincipalDesc and AuthorizationUtils.
> We should avoid exposing that to all Authorization implementations, but also 
> make the ability to customize the mapping of internal classes to the public 
> api classes possible for Apache Sentry (incubating).
