Harsh J updated MAPREDUCE-4415:
-------------------------------
Description:
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.
