Philipp Moritz commented on ARROW-4024:
---------------------------------------
I think it's fine to drop support for 0.27. I just wanted to point it out
because from
[https://github.com/apache/arrow/blob/9da458437162574f3e0d82e4a51dc6c1589b9f94/python/setup.py#L45]
[https://github.com/apache/arrow/blob/9da458437162574f3e0d82e4a51dc6c1589b9f94/python/setup.py#L578]
it looks like 0.27 is supported.
