Subject [jira] [Commented] (HADOOP-13345) S3Guard: Improved Consistency for S3A
Date Thu, 05 Jan 2017 17:08:58 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15801890#comment-15801890
] 

Chris Nauroth commented on HADOOP-13345:
----------------------------------------

I would prefer to see HADOOP-13589 completed before merge.  Being able to run the existing
S3A test suite with S3Guard enabled would help ensure that we're maintaining the existing
semantics as much as possible as we iterate further on the code.

> This issue proposes S3Guard, a new feature of S3A, to provide an option for a stronger
consistency model than what is currently offered.  The solution coordinates with a strongly
consistent external store to resolve inconsistencies caused by the S3 eventual consistency
model.
