Wangda Tan commented on YARN-5881:
----------------------------------
[~sunilg],
For the configurations of the absolute min/max resource, I suggest to make it
to be more compacted, for example:
{code}
${queue-path}.min/max-resource = <memory=10G,vcores=2,disk=1G>
{code}
And in the future we can support per-resource-type capacities in percentage as
well:
{code}
${queue-path}.(maximum-)capacity = <memory=70,vcores=30>
{code}
To me this will be better than flatten all resource types in your prototype
patch.
Thoughts?

> Currently, Yarn RM supports the configuration of queue capacity in terms of a
> proportion to cluster capacity. In the context of Yarn being used as a public
> cloud service, it makes more sense if queues can be configured absolutely.
> This will allow administrators to set usage limits more concretely and
> simplify customer expectations for cluster allocation.
