and Job.getInstance(Configuration, jobName) are now available across both
releases to avoid porting pain. (was: Backported new APIs to get a Job object
to 1.x from 2.x: Job.getInstance(), Job.getInstance(Configuration) and
Job.getInstance(Configuration, jobName))

> 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
> Fix For: 1.2.0
>
> 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 the regular ctors in a 1.x release, this is not an
> incompatible change in any way.
