Jason Lowe commented on MAPREDUCE-5870:
---------------------------------------
It would be nice to cleanup most of the checkstyle nits, as there are a lot of
switch statements without default clauses that were added. I realize
semantically we're covered since the fall-through case returns some default
value or throws, but we can trivially remove the warning by having an explicit
default clause that explicitly breaks or move the fallthrough code into that
default case.
Other than that latest patch looks good to me.

> 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)
