URL: https://issues.apache.org/jira/browse/ARROW-4024
Project: Apache Arrow
Issue Type: Improvement
Reporter: Philipp Moritz
On the latest master, I'm getting the following error:

Error compiling Cython file:

With 0.29.0 it is working. This might have been introduced in
[https://github.com/apache/arrow/commit/12201841212967c78e31b2d2840b55b1707c4e7b]
but I'm not sure.
