--------------------------------------------
Summary: Pandas MultiIndex renamed labels to codes (pd 0.24)
Key: ARROW-3953
URL: https://issues.apache.org/jira/browse/ARROW-3953
Project: Apache Arrow
Issue Type: Bug
Components: Python
Reporter: Joris Van den Bossche
Assignee: Joris Van den Bossche
Pandas deprecated the `MultiIndex.labels` in favor of `MultiIndex.codes`
([https://github.com/pandas-dev/pandas/pull/23752).] In the pandas
parquet/feather tests, we are now seeing warnings about this (and I assume
there will be warnings as well in pyarrow tests if running on pandas master).
