Sandy Ryza commented on YARN-1004:
----------------------------------
Uploaded a patch that adds "fair", "capacity", and "fifo" to the minimum and
increment configs. The patch turned out to require quite a few changes. I
wasn't sure how to deal with the slots-millis job counter - it seems like it
doesn't make sense in the context of MR2 - so I removed it. If this would
delay the release I'm not sure it's worth it.
[~tucu], you worked on the per-scheduler separation of these configs. Any
thoughts?
> yarn.scheduler.minimum|maximum|increment-allocation-mb should have scheduler

> Key: YARN-1004
> URL: https://issues.apache.org/jira/browse/YARN-1004
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: scheduler
> Affects Versions: 2.1.0-beta
> Reporter: Sandy Ryza
> Attachments: YARN-1004.patch

> As yarn.scheduler.minimum-allocation-mb is now a scheduler-specific
> configuration, and functions differently for the Fair and Capacity
> schedulers, it would be less confusing for the config names to include the
> scheduler names, i.e. yarn.scheduler.fair.minimum-allocation-mb,
> yarn.scheduler.capacity.minimum-allocation-mb, and
> yarn.scheduler.fifo.minimum-allocation-mb.
> The same goes for yarn.scheduler.increment-allocation-mb, which only exists
> for the Fair Scheduler, and yarn.scheduler.maximum-allocation-mb, for
> consistency.
> If we wish to preserve backwards compatibility, we can deprecate the old
> configs to the new ones.
