thswlsqls opened a new pull request, #8960:
URL: https://github.com/apache/paimon/pull/8960

   ### Purpose
   
   fix #8959
   
   - Override `listFilesIterative(Path, boolean)` in 
`org.apache.paimon.obs.HadoopCompliantFileIO` to delegate to Hadoop 
`OBSFileSystem.listFiles(path, recursive)`, so recursive listing uses OBSA's 
bulk listing instead of the `FileIO` default's one `listStatus` per directory.
   - Parity gap: `oss`, `s3`, `jindo` and core `HadoopFileIO` already have this 
override. Ported verbatim from `oss`, identical to jindo `0cc45257a`.
   - Returned set is unchanged (files only). Order becomes flat instead of BFS, 
and `FileNotFoundException` for a missing path surfaces eagerly — matching 
core/oss/s3/jindo.
   
   ### Tests
   
   - No test added: this module has no `src/test` and OBS has no local 
emulator. Precedent: gs #8559 (same class) and jindo `0cc45257a` merged without 
tests.
   - `mvn -pl paimon-filesystems/paimon-obs-impl -DfailIfNoTests=false clean 
install` — BUILD SUCCESS (checkstyle, spotless, enforcer).
