Wangda Tan commented on YARN-9116:
----------------------------------
[~aihuaxu],
This sounds like a plan, but existing maximum memory, etc. is defined inside
yarn-site.xml. And given we will have multiple resource types support like GPU.
I suggest to make the default maximum capacity definition use absolute values
for all types.
The name of the config could be:
{code:java}
<property>
<name>yarn.scheduler.capacity.default-queue-maximum-capacity</name>
<value>memory=20G,vcores=20,gpu=3</value>
</property>{code}
You can reuse implementation
org.apache.hadoop.yarn.submarine.client.cli.CliUtils#createResourceFromString
from trunk (and move it to common place if you think it is required).
Thoughts?

> Capacity Scheduler: add the default maximum-allocation-mb and

> Key: YARN-9116
> URL: https://issues.apache.org/jira/browse/YARN-9116
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: capacity scheduler
> Affects Versions: 2.7.0
> Reporter: Aihua Xu
> Assignee: Aihua Xu
> Priority: Major
>
> 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.
