- Protect getTaskDiagnostics() APIs also w.r.t access control.
- If a user gets an access control error, he should be informed about the
configured ACLs for the job.
- Make the ACL part of the JobStatus object so that it is visible to all
interested parties who might be interested (including the command line to get
the job status). Also, the CompletedJobStatusStore can make use of this and
enforce access control..

Done
bq. ACLs for jobs should be displayed as part of jobdetails (the front page for
jobs where all high level info is displayed).
This will be done as part of MAPREDUCE-1455.
bq. Can we have the default ACL for job view enabled for the groups the user
belongs to?
This is difficult to do without introducing SPECIAL case values ACLs, which
itself is tricky and I'm postponing for future as per need.
Leaving that aside, other changes in the patch include:
- CompletedJobStore is fixed now to respect ACLs. And because of the new
JobStatus objects, JT cannot read JobStatus by previous versions of JT, and
hence this is an incompatible change.
- Refactored the ACLs related methods into a new class JobACLsManager which
acts as an interface between JT and any component that needs job-level
authorization.
- JobStatus is modified to include ACLs. ClientProtocol's version is bumped up
too - another incompatible change.
- Added tests to verify the changes in CompletedJobStore.

> It would be good to define the notion of job permissions analogous to file
> permissions. Then the JobTracker can restrict who can "read" (e.g. look at
> the job page) or "modify" (e.g. kill) jobs.
