Subject [jira] [Updated] (YARN-2385) Adding support for move all applications from a source queue to destination queue
Date Wed, 06 Aug 2014 00:23:12 GMT

     [ https://issues.apache.org/jira/browse/YARN-2385?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Subramaniam Venkatraman Krishnan updated YARN-2385:
---------------------------------------------------

    Description: This is a parallel JIRA to YARN-2378. Fair scheduler already supports moving
a single application from one queue to another. This will add support to move all applications
from the specified source queue to target.  (was: The CapacityScheduler is a rather static
at the moment, and refreshqueue provides a rather heavy-handed way to reconfigure it. Moving
towards long-running services (tracked in YARN-896) and to enable more advanced admission
control and resource parcelling we need to make the CapacityScheduler more dynamic. This is
instrumental to the umbrella jira YARN-1051.

Concretely this require the following changes:
* create queues dynamically
* destroy queues dynamically
* dynamically change queue parameters (e.g., capacity) 
* modify refreshqueue validation to enforce sum(child.getCapacity())<= 100% instead of
==100%

We limit this to LeafQueues. )
