Description

Our project is integrating sentry and we find a problem when we stop sentry service(or make the sentry service crashed) after initialize HadoopGroupResourceAuthorizationProvider. That is to say SimpleDBProviderBackend can't throw exception and only return an ImmutableSet which size is 0 when sentry service down. We found that the method getPrivileges in SimpleDBProviderBackend catch the exception and just print the message like "Unable to obtain privileges from server: ". Is that make sense. The problem is the module which use sentry cannot get clearly reason that sentry service crash or use has not permission to some hive table.
