> 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.
