[jira] [Commented] (HADOOP-13447) S3Guard: Refactor S3AFileSystem
to support introduction of separate metadata repository and tests.
[ https://issues.apache.org/jira/browse/HADOOP-13447?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15403062#comment-15403062 ]
Chris Nauroth commented on HADOOP-13447:
----------------------------------------
The scope of this patch is intended to be purely refactoring pre-work with no logic changes to S3A. Depending on the final outcome, we may want to consider bringing the refactoring right into the main branches (trunk and branch-2). That will help with code maintenance on the main branches and minimize merge conflicts while merging trunk to the feature branch.

> 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.
