> Sasha helped in finding this bug. Looks like dropping a database/table does
> no longer clean up the privileges associated with it.
> This problem is because of:
> https://github.com/apache/sentry/blob/sentry-ha-redesign/sentry-provider/sentry-provider-db/src/main/java/org/apache/sentry/service/thrift/HMSFollower.java#L126-L127
> {code}
> final HiveConf hiveConf = new HiveConf();
> hiveInstance =
> hiveConf.get(HiveAuthzConf.AuthzConfVars.AUTHZ_SERVER_NAME.getVar());
> {code}
> With the latest redesign, we are only setting this property on Hive's
> (sentry-site.xml) and not on Sentry's (sentry-site.xml).
> So during permission grants, Hive ensures to supply the *server1* for
> permission updates. But when we drop the table/database that has the perms
> attached, it goes through HMSFollower and this code sets the property as NULL
> as sentry-site.xml doesn't have this set. So it attempts to remove
> permissions with NULL server setting and this always returns without deleting
> anything.
> We need to ensure that the corresponding property is set on both (Sentry,
> Hive) sentry-site.xml to ensure referring to proper privileges.
