zhuqi updated YARN-10524:
-------------------------
Description:
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 ?
