Yufei Gu commented on YARN-7077:
--------------------------------
Thanks [~ajisakaa] for filing this. It makes more sense to me to remove or
comment these in yarn-site.xml of SLS.
{code}
<property>
<name>yarn.resourcemanager.scheduler.monitor.enable</name>
<value>true</value>
</property>
<property>
<name>yarn.resourcemanager.scheduler.monitor.policies</name>
<value>org.apache.hadoop.yarn.server.resourcemanager.monitor.capacity.ProportionalCapacityPreemptionPolicy</value>
</property>
{code}
yarn.resourcemanager.scheduler.monitor.enable is false by default, and not
necessary used by FS.
