### Search before asking - [x] I searched in the issues and found nothing similar. ### Paimon version master, commit `56561540f88a224991f86a3212a357857d1e31f9` ### Compute Engine PyPaimon, Python 3.12.6 / PyArrow 19.0.1, local filesystem. ### Minimal reproduce step 1. Create a Parquet table with data evolution and row tracking enabled. 2. Write one row through `DataVectorWriter` or `DedicatedFormatWriter`. 3. During `prepare_commit()`, inject an `OSError` from `file_io.get_file_size()` after confirming that the output file exists. 4. Inspect the table directory after `prepare_commit()` raises the error. The newly written Parquet file remains. Both writers write the normal data file before returning its `DataFileMeta`. If reading the file size fails, the caller receives no metadata and cannot track the file for cleanup. ### What doesn't meet your expectations? The writer should remove the current output file when it fails before returning the file metadata. Instead, it leaves an unreferenced file in the table directory. ### 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.
