What's Wrong?

Setup a k8s cluster with FE/BE and add arrow flight ports. You can tell the BE that it has public_host and arrow-flight-proxy-port just fine. But you cannot do the same for the FE. It returns its internal name and redirects the client to that name to pull data (such as from show tables or use mydatabase). For queries that return from BE it runs fine, but not those from FE.

There should be a similar public_host and arrow flight proxy port for the FE, not just the BE.

What You Expected?

A setting in the FE that allows a public host and port to be selected when the driver returns a host for arrow data retrieval. And likely similarly for other URI for web data access.

How to Reproduce?

you cannot do this, the settings are missing.

Anything Else?

please?
