Interface HiveAuthorizer

All Known Implementing Classes:

HiveAuthorizerImpl

@InterfaceAudience.LimitedPrivate(value="")
@InterfaceStability.Evolving
public interface HiveAuthorizer

Interface for hive authorization plugins. Used by the DDLTasks for access control statement, and for checking authorization from Driver.doAuthorization() This a more generic version of HiveAuthorizationProvider that lets you define the behavior of access control statements and does not make assumptions about the privileges needed for a hive operation. This is referred to as V2 authorizer in other parts of the code.
