-------------------------------------------------------------
I don't think there should be other databases under {{/apps/hive/warehouse}}
directory if that is a concern. The {{default}} database points to
{{/apps/hive/warehouse}}, and new databases are created under that directory as
well by default, but you have the option to create a new database pointing to a
very different directory. I mean that way we could avoid this issue.

> Key: SPARK-29078
> URL: https://issues.apache.org/jira/browse/SPARK-29078
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Mihaly Toth
> Priority: Major
>
> Similarly to SPARK-20256, in {{SharedSessionState}} when
> {{GlobalTempViewManager}} is created, it is checked that there is no database
> exists that has the same name as of the global temp database (name is
> configurable with {{spark.sql.globalTempDatabase}}) , because that is a
> special database, which should not exist in the metastore. For this, a read
> permission is required on the warehouse directory at the moment, which on the
> other hand would allow listing all the databases of all users.
> When such a read access is not granted for security reasons, an access
> violation exception should be ignored upon such initial validation.
