------------------------------------
Hi [~jlowe] [~jianhe] [~eepayne]
I thought of bringing up a point we discussed earlier as I have one more
concern. To keep priority in JobStatus, and also to contact only AM (not RM) to
get JobStatus, we had discussed on updating priority to AM from RM through
heartbeat.
However, other than updating JobStatus, I am not finding any other good useful
reason for AM to know its own priority in RM. Do you see any more advantages
for AM knowing its priority(may be other than MapReduce AM also).

> Job Prioirty can be set from client side as below [Configuration and api].
> a. JobConf.getJobPriority() and
> Job.setPriority(JobPriority priority)
> b. 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.
