Subject [jira] [Updated] (YARN-2069) Add cross-user preemption within CapacityScheduler's leaf-queue
Date Tue, 24 Jun 2014 21:44:29 GMT

     [ https://issues.apache.org/jira/browse/YARN-2069?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mayank Bansal updated YARN-2069:
--------------------------------

    Attachment: YARN-2069-trunk-2.patch

Thanks for the review.

I don't have any easy way now to seprate the YARN-2022 and this patch as I am changing the
same code and run it through junkins.
I will rebase this patch once YARN-2022 is committed.

Thanks,
Mayank

> Preemption today only works across queues and moves around resources across queues per
demand and usage. We should also have user-level preemption within a queue, to balance capacity
across users in a predictable manner.
