> Intermittent failure of LocatedFileStatusFetcher.getFileStatuses(), which is using globStatus to find files.
> I'd say "turn s3guard on" except this appears to be the case, and the dataset being read is
> over 1h old.
> Which means it is harder than I'd like to blame S3 for what would sound like an inconsistency
> We're hampered by the number of debug level statements in the globber code being approximately none; there's no debugging to turn on. All we know is that globFiles returns null without any explanation.
