--------------------------------------

             Summary: Allow Sentry column authorization for Kudu tables
                 Key: IMPALA-5489
                 URL: https://issues.apache.org/jira/browse/IMPALA-5489
             Project: IMPALA
          Issue Type: New Feature
          Components: Frontend
    Affects Versions: Impala 2.8.0
            Reporter: Matthew Jacobs


In IMPALA-4000 we added basic authorization support for Kudu tables, but it had several limitations:
* Only the ALL privilege level can be granted to Kudu tables.
  (Finer-grained levels such as only SELECT or only INSERT are not supported.)
* Column level permissions on Kudu tables are not supported.
* Only users with ALL privileges on SERVER may create external Kudu tables.

We should relax some of these requirements, notably we should allow column level permissions.
There doesn't appear to be any technical reason we cannot do so.
