   @stoty Yetus does have some issue applying changes when the changes are 
beyond a certain point. I reported it some time back:
   
https://issues.apache.org/jira/browse/YETUS-719?focusedCommentId=17874835&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17874835
   
   You can temporarily hack it by c-picking this commit & revert it once you 
get the result from Yetus:
   
https://github.com/ayushtkn/hadoop/commit/bee603ed278eb0978af5822d19bf3c1c5704ba13
   
   See, if it helps :-)

> 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.
