François Chareyron updated ARROW-18225:
---------------------------------------
Description:
When using {{write_metadata}}, {{kwargs}} can be used to pass a FileSystem to a
ParquetWriter. However, those {{kwargs}} are not passed to {{read_metadata}}
later on despite the function accepting a filesystem argument.
This creates an error when trying to write metadata on a S3FileSystem for
example.
{code:python}
def write_metadata(schema, where, metadata_collector=None, **kwargs):
writer = ParquetWriter(where, schema, **kwargs)
writer.close()
if metadata_collector is not None:
metadata = read_metadata(where) # kwargs should be passed here
for m in metadata_collector:
metadata.append_row_groups(m)
metadata.write_metadata_file(where) # kwargs should be passed here
{code}
{code:python}
def read_metadata(where, memory_map=False, decryption_properties=None,
filesystem=None):
...{code}
