Qi Zhu commented on YARN-10524:
-------------------------------
Thanks [~gandras] for concern.
I think YARN-9936 will cover all this use cases:
# Multi capacity vector.
# Multi weight vector.
# Multi absolut vector.
> Support multi resource type based weight mode in CS.

> Key: YARN-10524
> URL: https://issues.apache.org/jira/browse/YARN-10524
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Qi Zhu
> Assignee: Qi Zhu
> Priority: Major
>
> In fair scheduler support multi resource based absolute and pecentage of the
> cluster.
> For minResources, maxResources, maxContainerAllocation and maxChildResources
> properties one can give the parameter in one of the following formats:
> * _Old format_: “X mb, Y vcores”, “X% cpu, Y% memory”, “X%”. When not a
> single percentage is provided, configuring both memory and cpu is mandatory,
> while other resource types are ignored, and set to zero.
> * _New format (recommended)_: “vcores=X, memory-mb=Y” or “vcores=X%,
> memory-mb=Y%”. As seen, in this format one can give either a percentage or an
> integer resource value without units. In the latter case the units will be
> inferred from the default units configured for that resource. This format is
> required when resources other than memory and CPU are specified. Any
> unspecified resource will be set to 0 in case of minResources, or to the
> maximum for that resource in case of maxResources, maxContainerAllocation and
> maxChildResources.
> We should to discuss how to do in CapacityScheduler ?
