> FileOutputFormat to support configurable FileOutputCommitter factory
> --------------------------------------------------------------------

>                 Key: MAPREDUCE-6823
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6823
>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: mrv2
>    Affects Versions: 3.0.0-alpha2
>         Environment: Targeting S3 as the output of work
>            Reporter: Steve Loughran
>            Assignee: Steve Loughran
>         Attachments: HADOOP-13786-HADOOP-13345-001.patch

> In HADOOP-13786 I'm adding a custom subclass for FileOutputFormat, one which can talk
direct to the S3A Filesystem for more efficient operations, better failure modes, and, most
critically, as part of HADOOP-13345, atomic commit of output. The normal committer relies
on directory rename() being atomic for this; for S3 we don't have that luxury.
> To support a custom committer, we need to be able to tell FileOutputFormat (and implicitly,
all subclasses which don't have their own custom committer), to use our new {{S3AOutputCommitter}}.
> I propose: 
> # {{FileOutputFormat}} takes a factory to create committers.
> # The factory to take a URI and {{TaskAttemptContext}} and return a committer
> # the default implementation always returns a {{FileOutputCommitter}}
> # A configuration option allows a new factory to be named
> # An {{S3AOutputCommitterFactory}} to return a  {{FileOutputCommitter}} or new {{S3AOutputCommitter}}
depending upon the URI of the destination.
> Note that MRv1 already supports configurable committers; this is only the V2 API
