JigaoLuo opened a new issue, #7616:
URL: https://github.com/apache/arrow-rs/issues/7616
**Describe the bug**
I recently tested the encoding_stats feature #7341 in the Parquet writer
(thank you for the PR #7354 !) and noticed an issue when using the
`parquet-rewrite` tool.
Rewritten files do not include `encoding_stats` in the footer. I’m seeking
clarification on whether this is a configuration issue or a bug. I’m unsure
what’s causing this. If this isn’t expected behavior, this issue is a bug
report. If I’ve overlooked something obvious, please correct me. Thank you.
**To Reproduce**
```
$ parquet-rewrite ... # I rewrite a parquet file
$ parquet footer generated.parquet | grep "encodingStats"
"encodingStats" : null,
....
"encodingStats" : null,
```
The parquet tool I used is from `parquet-java` :
https://github.com/apache/parquet-java/tree/master/parquet-cli
**Expected behavior**
Should not be null in the footer.
