             Summary: Impala's Invalidate Metadata should require less privileges
                 Key: SENTRY-189
                 URL: https://issues.apache.org/jira/browse/SENTRY-189
             Project: Sentry
          Issue Type: Bug
    Affects Versions: 1.2.0
            Reporter: Gwen Shapira


Right now, Impala's "invalidate metadata" is only available to users with "server" privilege.

The problem is that "invalidate metadata" has to run every time any change to the data is made. So everyone who has any privilege to write / modify any table in any DB has to be able to invalidate metadata.

With current privilege model, they need to call an admin to invalidate metadata before they can view data they just loaded.
