    Attachment: HADOOP-5048-1.patch

Attaching patch which does following:


* Changed the internal data-structure name from jobList to waitingJobs.
* Changed method names addJob, removeJob, getJob to reflect the change to include Waiting
in method name.
* Added logic to remove jobs from waiting job queue in job queue manager.


* Changed the initialized job list to accept JobInProgress instead of JobID.
* Moved the job clean up code into a separate method.
* Breaking out of the jobs list if the maximum number of jobs for the queue limit has been
reached. (Based on offline discussion with Vivek and Amar).


* Changed test case now to test with actual JobInProgress objects
* Added a new testcase to test conditions of Job removal.

"Successful", but both jobs were also being on jobqueue_details.jsp page for longtime e.g
up to 10 -15 mins after I restarted JobTracker.
> Before killing the jobs, status of both jobs was running and no task of from them was
