Subject [jira] [Updated] (YARN-3969) Allow jobs to be submitted to reservation that is active but does not have any allocations
Date Thu, 23 Jul 2015 23:14:05 GMT

     [ https://issues.apache.org/jira/browse/YARN-3969?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Subru Krishnan updated YARN-3969:
---------------------------------
    Attachment: YARN-3969-v1.patch

Attaching a simple patch that skips the overriding of max system apps for dynamic ReservationQueues
based on their absolute capacity to allow accepting & queuing jobs against the reservation
till resources are allocated.

> YARN-1051 introduces the notion of reserving resources prior to job submission. A reservation
is active from its arrival time to deadline but in the interim there can be instances of time
when it does not have any resources allocated. We reject jobs that are submitted when the
reservation allocation is zero. Instead we should accept & queue the jobs till the resources
become available.
