> By default, prevent shadowing of system schemas.
> ------------------------------------------------
>
> Key: SPARK-55964
> URL: https://issues.apache.org/jira/browse/SPARK-55964
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 4.2.0
> Reporter: Serge Rielau
> Priority: Major
> Labels: pull-request-available
>
> With the introduction of SYSTEM.BUILTIN and SYSTEM.SESSION to allow
> qualification fo routines and relations we are now faced with the dilema
> that, there can be persisted schemas with name SESSION and BUILTIN.
> For security it is desirable that e.g. builtin.current_user() resolves to
> system.builtin.current_user() and not a potentially malicious
> main.builtin.current_user().
> Here we will, by default ensure the desired order of SYSTEM catalog first,
> while providing a config to change it back.
