Amareshwari Sriramadasu updated MAPREDUCE-118:
----------------------------------------------
Attachment: patch-118-2.txt
Moved the setting of JobID from Job's constructor to submit method, because
after MAPREDUCE-1505, the proxy should be created lazily at the submit time.
JobID is not available if the job is not submitted.
Main code changes are in Job.java and JobContextImpl.java. Other changes are
replacing calls to getID() with getJobID().
> Job.getJobID() will always return null

> JobContext is used for a read-only view of job's info. Hence all the readonly
> fields in JobContext are set in the constructor. Job extends JobContext. When
> a Job is created, jobid is not known and hence there is no way to set JobID
> once Job is created. JobID is obtained only when the JobClient queries the
> jobTracker for a job-id., which happens later i.e upon job submission.
