[jira] [Created] (HADOOP-15107) Prove the correctness of the new committers, or fix where they are not correct

Steve Loughran created HADOOP-15107:
---------------------------------------

             Summary: Prove the correctness of the new committers, or fix where they are not correct
                 Key: HADOOP-15107
                 URL: https://issues.apache.org/jira/browse/HADOOP-15107
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 3.1.0
            Reporter: Steve Loughran
            Assignee: Steve Loughran


I'm writing about the paper on the committers, one which, being a proper paper, requires me to show the committers work.

# define the requirements of a "Correct" committed job (this applies to the FileOutputCommitter too)
# show that the Staging committer meets these requirements (most of this is implicit in that it uses the V1 FileOutputCommitter to marshall .pendingset lists from committed tasks to the final destination, where they are read and committed.
# Show the magic committer also works.

I'm now not sure that the magic committer works.
