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

HADOOP-13852 allows hadoop to be declare a different version in its version-info than in the
POM. This is currently needed to allow spark to act as a regression test for the s3guard work.

I've already got it in the HADOOP-13786 branch, but by putting it into the base s3guard branch
lets me test dynamodb and other patches, while the committer code is still a WiP

> 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.
