---------------------------------------
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.
