Subject [jira] [Commented] (HADOOP-13345) S3Guard: Improved Consistency for S3A
Date Fri, 09 Sep 2016 21:34:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15478327#comment-15478327
] 

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

Based on the most recent discussion here about simplifying the notion of policy, I have resolved
as invalid sub-tasks HADOOP-13450 and HADOOP-13451.  I expect the previous intended scope
of these issues will be small enough that we can combine it into the metadata store implementation
sub-tasks and possibly a few other sub-tasks to track integration back into {{S3AFileSystem}}.

> 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.
