> The spark statistics tracking doesn't correctly assess the size of the uploaded files as it only calls getFileStatus on the zero byte objects -not the yet-to-manifest files.
> Everything works with the staging committer purely because it's measuring the length of the files staged to the local FS, not the unmaterialized output.
