             Summary: add output committer which uses s3guard for consistent O(1) commits to S3
                 Key: HADOOP-13786
                 URL: https://issues.apache.org/jira/browse/HADOOP-13786
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 3.0.0-alpha2
            Reporter: Steve Loughran
            Assignee: Steve Loughran


A goal of this code is "support O(1) commits to S3 repositories in the presence of failures". Implement it, including whatever is needed to demonstrate the correctness of the algorithm. (that is, assuming that s3guard provides a consistent view of the presence/absence of blobs, show that we can commit directly).

I consider ourselves free to expose the blobstore-ness of the s3 output streams (ie. not visible until the close()), if we need to use that to allow us to abort commit operations.
