URL: https://github.com/apache/hadoop/pull/2257#issuecomment-696773775


   Surprisingly large mount of merge problems surfacing here, not in the 
production code but in the tests. A sign of my patches all going near the same 
code you've worked on.
   
   I'm going to move the new inner classes in S3ATestUtils out of there and 
into their own classes in o.a.h.fs.s3a.test; reduces the diff to S3ATestUtils 
(which is often a source of spurious merge pain), so once isolated, less long 
term suffering. 
   
   Doing that in #2310 which is a high priority change for me
