> Key: IMPALA-6521
> URL: https://issues.apache.org/jira/browse/IMPALA-6521
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 2.12.0
> Reporter: Lars Volker
> Assignee: Fredy Wijaya
> Priority: Major
> Labels: ramp-up, supportability
>
> Flags can be defined as hidden, which hides them from the help output.
> However, they are also hidden from /varz and from the logs during startup.
> This seems contradictory; we should make sure that we log it if a user
> enables a hidden flag / feature.
> We could even consider adding a warning to the log and to the main debug page
> if hidden / experimental features are enabled.
