Subject [jira] [Commented] (HADOOP-13345) S3Guard: Improved Consistency for S3A
Date Fri, 04 Aug 2017 13:56:02 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16114392#comment-16114392

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

# I get intermittent bad  request on that list directory test too...never worked out why,
s3 ireland.
# what do you need me to do?

How about you attach it as a .patch under the phase I release JIRA, HADOOP-13998 (which I
just renamed), and see what yetus says...no doubt there'll be some auditing of all its warnings,
which will take an iteration or two, then we can vote for the big merge, which will be a 2
+1 vote requirement. After its in, we can do a branch-2 version which will have to switch
lambda-expressions into anon classes; IntelliJ will do that for us

> 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.
