Devaraj Das commented on MAPREDUCE-1307:
----------------------------------------
Dhruba, the FS permission doesn't support some use cases as Hemanth outlined in
his last comment. While I don't think that those are likely cases, I also think
that it makes sense to do something that doesn't tie us to the FS permission
model. Should we later discover that we have to move to the ACL model to
support some use case, it would be a difficult switch and painful for users..

> 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.
