Description

When there is an error or failure, we can see at the bottom there are some redundant logs from hive server, which is confusing.

Research direction

Start with the Azure CI configuration for the fourth module and trace how the Hive server process and its logging dependencies are launched. Reproduce a failing run and inspect the SLF4J and log4j output. Done means the redundant Hive server messages no longer appear as CI errors while the underlying failure remains visible.
