[jira] [Updated] (YARN-1004)

with the scheduler type
[ https://issues.apache.org/jira/browse/YARN-1004?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alejandro Abdelnur updated YARN-1004:
-------------------------------------
Summary: yarn.scheduler.minimum|maximum|increment-allocation-mb should be prefixed with the scheduler type (was: yarn.scheduler.minimum|maximum|increment-allocation-mb should have scheduler)
> yarn.scheduler.minimum|maximum|increment-allocation-mb should be prefixed with the scheduler type

> 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
> Priority: Blocker
> 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.
