## Search before asking - [x] I searched the existing issues and found no duplicate request. ## Motivation When the Python backend detects an attempt to delete a file that is no longer present, the error reports only the file name. The partition and bucket are available in the manifest entry but omitted from the message, making the affected data harder to locate. For example, deleting the same file twice in partition `dt=2026-10-26`, bucket `0`, produces: ```text File deletion conflicts detected! Give up committing. Trying to delete file data-<uuid>-0.parquet which is not previously added. ``` The conflict is correctly rejected, but the error should also identify the partition and bucket. ## Solution Include readable partition values and the bucket in the missing-file deletion conflict message: ```text File deletion conflicts detected! Give up committing. Trying to delete file data-<uuid>-0.parquet which is not previously added (partition=dt=2026-10-26, bucket=0). ``` - Reuse the existing partition value conversion and escaping rules, including multi-column partitions and configured default partition names. - Use `<non-partitioned>` for non-partitioned tables. - Fall back to the original partition values if formatting fails, preserving the file name, bucket, and original conflict. - Keep conflict detection, exception types, and commit retry behavior unchanged. ## Anything else? Reproduced on `apache/paimon` master at `c12606b203de692db9d9423195d3a0c2cf1698e0`, using Python 3.11 and PyArrow 19.0.1. Minimal reproduction: 1. Create an append-only table partitioned by `dt`, with `write.native.enabled=false` and `commit.native.enabled=false`. 2. Write and commit a row with `dt=2026-10-26`. 3. Build a `CommitMessage` whose `deleted_files` contains the newly committed file, and commit it successfully. 4. Submit the same deletion through a new committer. It fails with the message above, without partition or bucket context. Related Java improvement: [#10566](https://github.com/apache/paimon/pull/10566). This request covers the Python backend’s missing-file deletion conflict path. ## 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.
