Summary: [Python] dask and kartothek integration tests are failing Key: ARROW-8342 URL: https://issues.apache.org/jira/browse/ARROW-8342 Project: Apache Arrow Issue Type: Bug Components: Python Reporter: Joris Van den Bossche Fix For: 0.17.0 The integration tests for both dask and kartothek, and for both master and latest released version of them, started failing the last days. Dask latest: https://circleci.com/gh/ursa-labs/crossbow/10629?utm_campaign=vcs-integration-link&utm_medium=referral&utm_source=github-build-link Kartothek latest: https://circleci.com/gh/ursa-labs/crossbow/10604?utm_campaign=vcs-integration-link&utm_medium=referral&utm_source=github-build-link I think both are related to the KeyValueMetadata changes (ARROW-8079). The kartothek one is clearly related, as it gives: TypeError: 'pyarrow.lib.KeyValueMetadata' object does not support item assignment And I think the dask one is related to the "pandas" key now being present twice, and therefore it is using the "wrong" one. -- This message was sent by Atlassian Jira (v8.3.4#803005)
