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.
> Make ResourceCalculator configurable for FairScheduler and FifoScheduler like
> CapacityScheduler

> Key: YARN-2367
> URL: https://issues.apache.org/jira/browse/YARN-2367
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 2.2.0, 2.3.0, 2.4.1
> Reporter: Swapnil Daingade
> Priority: Minor
>
> 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.
