As surfaced in T422963 and T419820, we sometimes need to give access to /wmf/data/hdfs/usage which is limited to analytics-admins group. We need to move this dataset to be readily available in superset so the dashboard using it would work.
Some context has been captured in a private conversation.
The dataset backing the usage dashboard has a lot more data (including the listing of all files), so it needs to be restricted to analytics-admins. We could add a pipeline that creates a derived dataset with just what we need, but this is more work than we want to do, especially as we plan to move to Ceph.
