> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.1.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major

> 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.
