URL: https://github.com/apache/hadoop/pull/2530#issuecomment-740536282
I have a more straightforward solution to this: S3A to implement the
FileSystem.getXAttr API call to return the headers. No risk to other
applications; all spark will need to do is check for the header before looking
for file length, swallow any exceptions raised in the API call and fall back to
getFileStatus. Less than 10 lines.

> 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.
