   > @zhixingheyi-tian , could you check the CI failure issues, especially the 
checkstyle issue reported?
   > 
   > And any specific reason that not landing on trunk first, and then 
cherry-pick to branch-3.3.3?
   
   Hi  @ChenSammi ,
   
   Thanks very much for your kind review.
   CI failure issues seems not related to my pull request.
   This patch also can be merged into trunk  branch, then cherry-pick to 
branch-3.3.3 or branch-3.3.
   I also created  one PR: https://github.com/apache/hadoop/pull/8241, for 
trunk branch.
   
   Thanks!

> Currently, the TestDFSIO benchmark hardcodes the InputFormat to 
> SequenceFileInputFormat.class in the runIOTest method. This limits 
> flexibility for users who want to test different InputFormat implementations' 
> performance, particularly CombineSequenceFileInputFormat which is essential 
> for handling small file scenarios efficiently.
