I have a similar issue.
pyarrow 14.0.2
```
parquet.write_metadata(
File ".../lib/python3.9/site-packages/pyarrow/parquet/core.py", line 3589,
in write_metadata
metadata.append_row_groups(m)
File "pyarrow/_parquet.pyx", line 807, in
pyarrow._parquet.FileMetaData.append_row_groups
RuntimeError: AppendRowGroups requires equal schemas.
The two columns with index 0 differ.
column descriptor = {
name: session_num,
path: session_num,
physical_type: INT64,
converted_type: UINT_64,
logical_type: Int(bitWidth=64, isSigned=false),
max_definition_level: 0,
max_repetition_level: 0,
}

All partitions have equal schemas. Example are taken from
