Harsh J updated MAPREDUCE-4415:
-------------------------------
Attachment: MAPREDUCE-4415.patch
A backport of 3 static methods with javadocs, and a smattering of test changes
to cover them (keeps-unchanged adequate older-style constructor tests, to
preserve coverage).
> Backport the Job.getInstance methods from MAPREDUCE-1505 to branch-1
> --------------------------------------------------------------------

> Key: MAPREDUCE-4415
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4415
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: mrv1
> Affects Versions: 1.0.0
> Reporter: Harsh J
> Assignee: Harsh J
> Attachments: MAPREDUCE-4415.patch

>
> In 2.x MR, the Job constructors have all been deprecated in favor of
> Job.getInstance() calls to get a Job object.
> However, these getInstance methods do not appear to be present in the 1.x MR
> API, and thereby may cause additional pain to users moving from 1.x to 2.x
> going forward.
> This patch proposes to add in the getInstance style of methods with suitable
> test coverage for both style of constructors, while not pulling in anything
> else from MAPREDUCE-1505 (as we lack 'Cluster' in 1.x). As we're not going to
> be deprecating in a 1.x release, this is not an incompatible change in any
> way.
