> As part of the Sentry integration, it will be necessary to flesh out the  [AuthzTokenPB|https://github.com/apache/kudu/blob/master/src/kudu/security/token.proto#L28] structure with relevant fields:
>  # The ID of the table which the token applies to
>  # The username which the attached privileges belong to
>  # The privileges
> Sentry has it's own privilege format [TSentryPrivilege|https://github.com/apache/sentry/blob/master/sentry-service/sentry-service-api/src/main/resources/sentry_policy_service.thrift#L47-L58], but we'll probably want to convert this into our own internal Protobuf-based format for the following reasons:
>  # The tokens will be used in the tablet servers to authorize client actions. Currently tablet servers don't use or link to Thrift libraries.
>  # The Sentry privilege structure references columns by name, whereas we will need to reference columns by ID in order to be robust to columns being renamed.
>  # Having our own format will make it easier to drop in alternate authorization providers in the future.
