Weiwei Yang updated YARN-9116:
------------------------------
Hadoop Flags: Reviewed
Fix Version/s: 3.3.0
Release Note: After this change, capacity scheduler queue is able to
inherit max-allocation from its parent queue. User can set queue-level
max-allocation on any level of queues, using configuration property
"yarn.scheduler.capacity.%QUEUE_PATH%.maximum-allocation". And this property
allows user to set max-resource-allocation for customized resource types, e.g
"memory=20G,vcores=20,gpu=3".

> YARN-1582 adds the support of maximum-allocation-mb configuration per queue
> which is targeting to support larger container features on dedicated queues
> (larger maximum-allocation-mb/maximum-allocation-vcores for such queue) .
> While to achieve larger container configuration, we need to increase the
> global maximum-allocation-mb/maximum-allocation-vcores (e.g. 120G/256) and
> then override those configurations with desired values on the queues since
> queue configuration can't be larger than cluster configuration. There are
> many queues in the system and if we forget to configure such values when
> adding a new queue, then such queue gets default 120G/256 which typically is
> not what we want.
> We can come up with a queue-default configuration (set to normal queue
> configuration like 16G/8), so the leaf queues gets such values by default.
