> The current implementation for JobTracker.getAllJobs() returns all submitted jobs in
any state, in addition to retired jobs. This list can be long and represents an unneeded overhead
especially in the case of clients only interested in jobs in specific state(s). 
> It is beneficial to include a refined version where only jobs having specific statuses
are returned and retired jobs are optional to include. 
> I'll be uploading an initial patch momentarily.
