----------------------------------
Summary: 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
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.
