Method Detail

getHiveAuthorizationTranslator

public HiveAuthorizationTranslator getHiveAuthorizationTranslator()
                                                           throws HiveAuthzPluginException

Description copied from interface: HiveAuthorizer

Get a HiveAuthorizationTranslator implementation. See HiveAuthorizationTranslator for details. Return null if no customization is needed. Most implementations are expected to return null. The java signature of the method makes it necessary to only return Object type so that older implementations can extend the interface to build against older versions of Hive that don't include this additional method and HiveAuthorizationTranslator class. However, if a non null value is returned, the Object has to be of type HiveAuthorizationTranslator
