------------------------------------------------------
Summary: Adding support for move all applications from a source
queue to destination queue
Key: YARN-2385
URL: https://issues.apache.org/jira/browse/YARN-2385
Project: Hadoop YARN
Issue Type: Sub-task
Components: capacityscheduler
Reporter: Subramaniam Venkatraman Krishnan
Assignee: Carlo Curino
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.
