Subject [jira] [Commented] (YARN-5392) Replace use of Priority in the Scheduling infrastructure with an opaque ShedulerKey
Date Tue, 26 Jul 2016 05:00:26 GMT

    [ https://issues.apache.org/jira/browse/YARN-5392?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15393230#comment-15393230

Arun Suresh commented on YARN-5392:

The remaining checkstyles are all related to method parameters / method length and variables
needing to be private, all of which were not introduced by this patch.
[~kasha], do let me know if you are fine with it...

> Based on discussions in YARN-4888, this jira proposes to replace the use of {{Priority}}
in the Scheduler infrastructure (Scheduler, Queues, SchedulerApp / Node etc.) with a more
opaque and extensible {{SchedulerKey}}.
> Note: Even though {{SchedulerKey}} will be used by the internal scheduling infrastructure,
It will not be exposed to the Client or the AM. The SchdulerKey is meant to be an internal
construct that is derived from attributes of the ResourceRequest / ApplicationSubmissionContext
/ Scheduler Configuration etc.
