hudi-bot opened a new issue, #15114:
URL: https://github.com/apache/hudi/issues/15114

   After rebasing Hudi's COW table onto `BaseFileOnlyRelation` from 
`HadoopFsRelation`, we lost very helpful file-scanning metrics like # of files 
scanned, total size of files scanned, etc.
   
    
   
   After some investigation, i've found out that this occurred b/c now instead 
of relying on `FileScan` node in Spark plans like we're before, it now uses 
`DataScan` node that doesn't provide such metrics.
   
   This unwanted transition occurred b/c Spark internally predicates on 
`HadoopFsRelation` to decide whether it's a `FileScan` or `DataScan`, and since 
we stopped using `HadoopFsRelation` Hudi relations now fall into the latter 
bucket
