[jira] [Created] (MAPREDUCE-4415) Backport the Job.getInstance
methods from MAPREDUCE-1505 to branch-1
Harsh J created MAPREDUCE-4415:
----------------------------------
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.

Harsh J commented on MAPREDUCE-4415:
------------------------------------
bq. -1 findbugs. The patch appears to introduce 218 new Findbugs (version 2.0.1-rc3) warnings.
Same count as the one I received on HDFS-3617 earlier today. None of these findbugs are caused by my code. Hence that -1 can be ignored for this patch.

------------------------------------------
Harsh - there are many more instances of 'new Job()' ?
Do you plan to fix all of them?

Posted by "Harsh J (JIRA)" <ji...@apache.org>.

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).

-------------------------------
Target Version/s: (was: 1.2.0)
Fix Version/s: 1.2.0
Release Note: Backported new APIs to get a Job object to 1.2.0 from 2.0.0. Job API static methods Job.getInstance(), Job.getInstance(Configuration) 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))
Hadoop Flags: Reviewed
Committing to branch-1, thanks Tom and Arun!

------------------------------------
Arun - I thought I'd leave some to not mess with test coverage for that ctor, as it has not been deprecated/replaced by this change. If you feel we should change it all, I'll go ahead. Let me know!
