> Sentry tries to synchronize the HMS operations to make sure that sentry
> server process the notifications for create/drop/alter table and databases
> before it receives permission grants/revokes on them. Blocking HMS threads to
> make sentry processes appropriate notifications makes sense but doing the
> same when full snapshot is taken doesn’t serve any purpose as sentry server
> doesn’t update sentry permissions based on HMS full snapshot. We can document
> that there sentry could have some stale permissions when there are any DDL
> operations performed at the time of snapshot creation.
