Subject [jira] [Commented] (HADOOP-13345) S3Guard: Improved Consistency for S3A
Date Wed, 04 Jan 2017 20:33:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15799249#comment-15799249

Aaron Fabbri commented on HADOOP-13345:

Happy new year [~stevel@apache.org] and [~liuml07].  I'd like to figure out the set of JIRAs
we want to resolve before merging the feature branch.  We've discussed before targeting basic
list consistency for the initial feature set.  It seems like the main features we need are:

- Any DynamoDB bugs (initialization stuff, etc).
- Basic CLI functionality. HADOOP-13650
- Multi-bucket improvements, including read-only buckets.  HADOOP-13876.  I think the solution
will be to tackle the per-bucket config JIRA HADOOP-13336

- Make sure testing is sorted.  Currently tests are good but a bit manual.  Do we want to
do HADOOP-13589 pre merge?

Post merge: 
- The rest of the JIRAs.

Let me know what you think.  Should we create a new "s3guard phase 2" umbrella JIRA so we
can start moving stuff over once we have consensus?

> 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
