Sandy Ryza resolved YARN-2367.
------------------------------

    Resolution: Not a Problem

Hi Swapnil,
The Fair Scheduler supports this through a different interface.  "Scheduling policies" can be configured at any queue level in the hierarchy.

In general, the FIFO scheduler lacks most of the advanced functionality of the Fair and Capacity schedulers.  My opinion is that achieving parity is a non-goal.  If you think this shouldn't be the case, feel free to reopen this JIRA under a name like "Support multi-resource scheduling in the FIFO scheduler" and we can discuss whether that's worth embarking on.

> The ResourceCalculator used by CapacityScheduler is read from a configuration file entry capacity-scheduler.xml yarn.scheduler.capacity.resource-calculator. This allows for custom implementations that implement the ResourceCalculator interface to be plugged in. It would be nice to have the same functionality in FairScheduler and FifoScheduler.
