### Search before asking - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. ### Paimon version 1.4 ### Compute Engine flink ### Minimal reproduce step 1. PyPaimon writes `snapshot-32494` atomically and leaves a temporary file: snapshot-32494d686aba1-b44a-40a4-a4f1-d854830aa5cb.tmp 2. Java scans the snapshot directory through `SnapshotManager` or `FileUtils.listVersionedFiles`. 3. Java treats the temporary file as a snapshot and throws: NumberFormatException: For input string: "32494d686aba1-b44a-40a4-a4f1-d854830aa5cb.tmp" <img width="983" height="427" alt="Image" src="https://github.com/user-attachments/assets/02376c41-de86-453b-a38b-f64eb6595b14"; /> ### What doesn't meet your expectations? Python and Java should use the same temporary-file naming convention. Temporary files should not be treated as versioned metadata files, and Java should skip invalid version filenames instead of throwing `NumberFormatException`. ### Anything else? _No response_ ### Are you willing to submit a PR? - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
