I see that Hive metastore doesn't provide the changelog (NOTIFICATION_LOG) for the authorization operations like GRANT , REVOKE etc..
I also assume in this case the Hive Replication doesn't replicate these events as they are not recorded as metastore events in the NOTIFICATION_LOG table. Is there any reason these events are not captured, or is it just a missing feature? I have created a JIRA as well to capture this: https://issues.apache.org/jira/browse/HIVE-27262
