> Job Priority support in MapReduce.
> 1. Job Priority can be set from client side as below (Configuration and api).
> - JobConf.getJobPriority() and
> JobConf.setJobPriority(JobPriority priority)
> - We can also use configuration
> "mapreduce.job.priority".
> Now this Job priority can be passed in Application Submission
> context from Client side.
> Here we can reuse the MRJobConfig.PRIORITY configuration.
> 2. CLI changes to support {{--set-priority}}. Run time change of JobPriority
> is also to be handled.
> 3. Change {{Job}} to have the support for {{setPriority}} and {{getPriority}}
> (getter is handled with JobStatus)
