Subject [jira] [Commented] (HADOOP-13345) S3Guard: Improved Consistency for S3A

    [ https://issues.apache.org/jira/browse/HADOOP-13345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15828156#comment-15828156

Steve Loughran commented on HADOOP-13345:
-----------------------------------------

I've created a JIRA to explicitly track the things people think is needed for the first preview/merge:
HADOOP-13998

I want the version marker in, as we mustn't let this get into the field without one: otherwise
the whole version marker logic is cripped from outset.

> 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.
