> For backwards compatibility, these methods should exist in both MR1 and MR2.
> Confusingly, these methods return the max memory and used memory of the
> jobtracker, not the entire cluster.
> I'd propose to add them to MR2 and return -1, and deprecate them in both MR1
> and MR2. Alternatively, I could add plumbing to get the resource manager
> memory stats.
