---------------------------------
Summary: Fill-out AuthzToken definition
Key: KUDU-2542
URL: https://issues.apache.org/jira/browse/KUDU-2542
Project: Kudu
Issue Type: Sub-task
Components: security
Affects Versions: 1.8.0
Reporter: Dan Burkert
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|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.
