Steve Loughran commented on HADOOP-13886:
-----------------------------------------
my test, I believe. It's using the s3 metrics to count the #of fake directory
operations, that is: measure side effects happening internally.
I think we'll just need to have this test disabled when s3guard is in charge,
as it's not creating things any more
