Subject [jira] [Commented] (HADOOP-13447) S3Guard: Refactor S3AFileSystem to support introduction of separate metadata repository and tests.
Date Mon, 15 Aug 2016 20:30:22 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13447?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15421618#comment-15421618

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

[~stevel@apache.org], this is another one that I'd like us to consider taking straight to
trunk and branch-2, similar to HADOOP-13446.  I think HADOOP-13252 should be committed first
though, so that the refactoring work here doesn't stomp on your credential provider chain
work.

> 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.
