Should we add a arrow::fs::AssertFileInfo(fs_.get(), path, FileType::NotFound); at the end? Personally I would probably also add an assertion that the container does exist before deleting it.

Should we add a arrow::fs::AssertFileInfo(fs_.get(), path, FileType::NotFound); at the end? Personally I would probably also add an assertion that the container does exist before deleting it.

Should we add a arrow::fs::AssertFileInfo(fs_.get(), path, FileType::NotFound); at the end? Personally I would probably also add an assertion that the container does exist before deleting it.
