Re: Why capacity scheduler not support DRF?
Hi,
I didn't see anyone respond to your question. If you already got a response,
please ignore this one.
The Capacity Scheduler does support DRF. You can specify which resource
calculator to use by setting the yarn.scheduler.capacity.resource-calculator
property:
<property>
<name>yarn.scheduler.capacity.resource-calculator</name>
<value>org.apache.hadoop.yarn.util.resource.DominantResourceCalculator</value>
</property>
The DefaultResourceCalculator is set by default. So if you want the DRF, you
need to set the resource-calculator property as shown above.
Hope that helps,
-Eric
