描述
### Describe the bug, including details regarding any error messages, version, and platform.
close() in end()'s finally runs before the writer is marked aborted, so a failure serializing indexes/bloom filters/footer flushes the incomplete stream. And withAbortOnFailure only catches IOException, so a RuntimeException/Error (e.g. OOM) never aborts at all. On non-rename storage this leaves a corrupt file at the final path that a retried task silently reuses. Affects the parquet-hadoop writer path on master, any platform.

调研方向
Start by locating ParquetFileWriter.end() and withAbortOnFailure in the parquet-hadoop writer path, then trace the finally block and failure handling around serialization and close(). Check existing writer-finalization tests, if present. Done means serialization failures, including non-IOException failures, abort without flushing an incomplete file to the final path.
