> Working on the minimal_builds I have found that when building arrow and pyarrow without DATASET nor PARQUET the following error happens:
> {code:java}
>     def test_parquet_invalid_version(tempdir):
>         table = pa.table({'a': [1, 2, 3]})
>         with pytest.raises(ValueError, match="Unsupported Parquet format version"):
> >           _write_table(table, tempdir / 'test_version.parquet', version="2.2")
> E           NameError: name '_write_table' is not defined
> pyarrow/tests/parquet/test_basic.py:52: NameError{code}
> This is the first test on the parquet/test_basic.py module.
> I have done some investigation and if I change the test order (move that test on the file), the test that fails is a different one, always the first test on the module.
> If I import (but not use)  from pyarrow.tests.parquet.common import pytestmark no test failures happen.
> There seems to be a bug on how the pytestmark is injected. I am creating a ticket because it seems it might require more than a MINOR fix.
