   @cnauroth @szetszwo Thank you for your responses! Regarding the issue with 
Yetus failing to compile, @ayushtkn  proposed a solution to handle large PRs. I 
suggest we first run this PR to test it, and if it’s suitable for splitting, we 
can submit it in parts.
   
   @stoty Thank you for your contribution! Please review the details of this 
commit. During development, we need to replace Yetus with Ayush's branch. If 
this PR is merged, we should revert this commit.

> Java 22 breaks Subject propagation for new Threads (when SecurityManager is 
> not enabled).
> Previously, the Subject set by Subject.doAs() / Subject.callAs() 
> automatically propagated to any new Threads created (via new Thread(), not 
> Executors).
> With JDK22, this is no longer the case, new Threads do NOT inherit the 
> Subject.
> As Hadoop heavily relies on the original behavior, we somehow need to solve 
> this problem.
