Fine-grained authorization

Kudu can be configured to enforce fine-grained authorization across servers. This ensures that users can see only the data they are explicitly authorized to see. Kudu supports this by leveraging policies defined in Apache Sentry 2.2 and later. Starting with Kudu 1.12.0, Kudu now supports fine-grained authorization by leveraging policies defined in Apache Ranger 2.1 and later.
