pitrou · xhochy · commit 5bb3d85e82a9 · 2018-05-16T18:13:05.000+02:00
There is a regression (*) in Pandas 0.23.0 that breaks test_parquet.py. Pandas does not have an actual "str" dtype anyway, so pass "object" instead. (*) pandas-dev/pandas#21083 Author: Antoine Pitrou <antoine@python.org> Closes #2051 from pitrou/ARROW-2589 and squashes the following commits: b581ef3 <Antoine Pitrou> ARROW-2589: Workaround regression in Pandas 0.23.0
