Philipp Moritz updated ARROW-1625:
----------------------------------
Description:
At the moment what happens when we serialize an OrderedDict and then
deserialize it, it will become a normal dict! This can be reproduced with
{code}
import pyarrow
import collections
d = collections.OrderedDict([("hello", 1), ("world", 2)])
type(pyarrow.serialize(d).deserialize())
{code}
which will return "dict". See also
https://github.com/ray-project/ray/issues/1034.
