Amareshwari Sriramadasu commented on MAPREDUCE-118:
---------------------------------------------------
JobID is accessible from job.getID(). Should we remove the method getJobID()
from JobContext? and suggest users to use getID?
> 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.
