Trino worker nodes fail to start when config.properties contain web ui specific properties

[thereisnospoon]

Hi,

I've been trying to provision a Trino cluster on top of AWS EMR. One thing I wanted to configure is to disable auth on Web UI by setting web-ui.authentication.type to fixed in config.properties file as per https://trino.io/docs/current/admin/properties-web-interface.html.

The problem is that when setting web-ui.authentication.type property for both master and worker nodes, the worker nodes cannot start. I'm getting the following errors:

2022-03-28T10:52:08.031Z	ERROR	main	io.trino.server.Server	Configuration is invalid
==========

Errors:

1) Configuration property 'web-ui.authentication.type' was not used
2) Configuration property 'web-ui.user' was not used

The easy solution would be removing the web-ui properties from config.properties on workers, but it looks like it's not easily done on managed cloud environments like Amazon EMR or Google Dataproc.

Wouldn't it make more sense to just ignore web-ui properties in case a node acts as a worker?

What's your trino version?

I've tested this on version 360

Workers don't run the UI so these configuration properties are not allowed.
