Wes McKinney commented on ARROW-8342:
-------------------------------------
Are there any problems beyond the return value of the {{.metadata}} property?
It seems like the simplest thing is to convert {{KeyValueMetadata}} to dict
when returning from this property
> [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
> Priority: Blocker
> 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.
