test_import_without_warning fails with packaging >= 20.5

[bnavigator]

test_import_without_warning does this:

subprocess.check_call([sys.executable, "-Werror", "-c", "import fastparquet"])

But with packaging >= 20.5 this raises a DeprecationWarning:

[   95s] E           subprocess.CalledProcessError: Command '['/usr/bin/python3.6', '-Werror', '-c', 'import fastparquet']' returned non-zero exit status 1.
...
[   95s] DeprecationWarning: Creating a LegacyVersion has been deprecated and will be removed in the next major release

This is due to https://github.com/pypa/setuptools/issues/2466 / https://github.com/pypa/packaging/issues/368

I advise you to try with arrow's hdfs interface.

yes, i prefer to use pyarrow, and it works with kerberos.
