The CI workflow run with tests that require additional secrets finished as failure: https://github.com/trinodb/trino/actions/runs/4233580804

This check can be skipped because directory is created implicitly when first file is created.

This should be part of the commit message

[pajaks]

This seems to be redundant check, as individual files (and implicitly directories) are created at this point. If location would be file it should fail during directory creation earlier.

This should be part of the commit message

[ebyhr]

nit: I would include "in Delta Lake" or something to commit titles.

[pajaks]

Commit message changed.

@ebyhr @findepi Could you run tests with secretes?

[ebyhr]

@pajaks Was there any change since last review except for the commit title? We don't need to run CI if the change is only commit title.

but these don't use secrets, so proceeding to merge
