Chris Nauroth commented on HADOOP-13447:
----------------------------------------

I'd like to propose merging this change back to branch-2.8 to simplify the process of back-porting patches and avoid merge conflicts.  I'll wait a few days for comments in case anyone objects.

> The scope of this issue is to refactor the existing {{S3AFileSystem}} into multiple coordinating classes.  The goal of this refactoring is to separate the {{FileSystem}} API binding from the AWS SDK integration, make code maintenance easier while we're making changes for S3Guard, and make it easier to mock some implementation details so that tests can simulate eventual consistency behavior in a deterministic way.
