   > * Apache Spark 4.0.0 RC2 makes this dependency optional intentionally due 
to [CVE-2024-23953](https://github.com/advisories/GHSA-p953-3j66-hg45). In RC2, 
The vulnerability only affected the production environments when the users 
allow it by installing the package intentionally.
   > * This PR will propagate `Apache Hive LLAP vulnerability` back to Apache 
Spark binary distribution again although this is not a regression from Apache 
Spark 3.
   > * After this PR, it's highly recommended to handle it internally in the 
production environments by patching it internal fork of Spark or Hive based on 
their own user situations.
   > 
   > I must admit that the AS-IS Apache Spark 4.0.0 RC2 was a bandage until 
Apache Spark upgrades its Hive dependency to Apache Hive 4.x. Every path 
(including this) has it own rational. So, thank you again.

   > From our production environment, we will opt-out still.
   
   After restoring this dependency, I think it would be best to have a place to 
document this known issue and provide recommendations to users, such as on the 
security.html page of our website, or in the 4.0 release notes.
