[jira] [Commented] (YARN-10923) Investigate if creating separate classes for Dynamic Leaf / Dynamic Parent queues makes sense

["András Győri (Jira)" <ji...@apache.org>]

András Győri commented on YARN-10923:
-------------------------------------

h2. Dynamic Queue related methods
 * setDynamicQueueProperties - it is also used by legacy AQC
 * isInactiveDynmicQueue
 * isDynamicQueue

h2. Analysis
 * Difference between dynamic and static queues is the templating system, which is located in setDynamicQueueProperties
 * A queue can be converted to static queue, which would be harder in case Dynamic Queues were extracted in to their own class
 * This change would only be meaningful if legacy AQC and flexible AQC were merged together, otherwise we would end up with two empty

> First, create 2 new classes: DynamicLeaf / DynamicParent.
> Then, gradually move AQC functionality from ManagedParentQueue / AutoCreatedLeafQueue.
> Revisit if AbstractManagedParentQueue makes sense at all.
> ManagedParent / Parent: Is there an actual need for the two classes?
> - Currently the two different parents can cause confusion and chaos
> - Can be a “back two the drawing board” task
> The ultimate goal is to have a common class for AQC-enabled parent and investigate if separate class for AutoCreatedLeafQueue is required.
