> 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.
