Review Comment:
Yes, it would be also nice to have an expiry time on it
> Introduce new plugin authentication modes
> -----------------------------------------
>
> Key: DRILL-8155
> URL: https://issues.apache.org/jira/browse/DRILL-8155
> Project: Apache Drill
> Issue Type: Improvement
> Components: Security
> Affects Versions: 1.20.0
> Reporter: Charles Givre
> Assignee: Charles Givre
> Priority: Major
> Fix For: Future
>
>
> At present, Drill storage plugins can use a shared set of credentials to
> access storage on behalf of Drill users or, in a subset of cases belonging to
> the broader Hadoop family, they can impersonate the Drill user when
> drill.exec.impersonation.enabled = true. An important but missing auth mode
> is [what is termed "user translation" in
> Trino|[https://docs.starburst.io/latest/security/impersonation.html].] Under
> user translation, the active Drill user is translated to a user known to the
> external storage by means of a translation table that associates Drill users
> with their credentials for the external storage. No support for user
> impersonation in the external storage is required in this mode. This ticket
> proposes that we add establish a design pattern that adds support for this
> auth mode to Drill storage plugins.
> Another present day limitation is that impersonation, for the plugins that
> support it, is toggled by a global switch. We propose here that the auth
> mode chosen for a plugin should be independent of the auth modes chosen for
> other plugins, by a move of this option into their respective storage configs.
> Finally, while a standardised means of choosing an authentication mode is
> desired, note that not every storage plugin needs to, or can, support every
> mode.
