URL: https://github.com/apache/hive-site/pull/24#issuecomment-2566482775
> If there is no difference in configuration/steps between installing Hive
4.0.1 on Hadoop 3.1 and on Hadoop 3.3.6, I don't think we need to write the
detailed configuration. We just need to add a note that **Hive 4.0.1can be
deployed safely against Hadoop version >3.1**.
@zhangbutao
No, Sir. Unlike the normal deployment, in this step we add all dependencies
of Hadoop 3.3.6+ in HIVE & TEZ because if we deploy HIVE4 in a lower version
Hadoop environment, we won't be able to use the jar packages and other
resources from the lower version Hadoop environment.
Additionally, while experienced developers might be able to explore
deployment solutions, many users do not have the relevant experience. Moreover,
both the HIVE deployment documentation and the official HIVE website imply that
Hadoop 3.3.6 is required for deploying HIVE4. Therefore, to increase the
adoption rate of HIVE4, I believe we still need to provide a separate
explanation for this matter.

> Currently, many users want to upgrade to HIVE4, but they are often limited by
> the fact that the version of their existing HADOOP cluster is too low to
> upgrade to HIVE4. But in fact, HIVE4 can work with lower versions of
> HADOOP.We should improve the documentation to show these users how to upgrade
> to HIVE4.
