Hello Jon,
I have the following yarn-site.xml :
<configuration>
<!-- Site specific YARN configuration properties -->
<property>
<name>yarn.acl.enable</name>
<value>0</value>
</property>
<property>
<name>yarn.resourcemanager.hostname</name>
<value>hadoopresourcemanager</value>
</property>
<property>
<name>yarn.nodemanager,aux-services</name>
<value>mapreduce_shuffle</value>
</property>
<property>
<name>yarn.nodemanager.resource.memory-mb</name>
<value>1536</value>
</property>
<property>
<name>yarn.scheduler.maximum-allocation-mb</name>
<value>1536</value>
</property>
<property>
<name>yarn.scheduler.minimum-allocation-mb</name>
<value>128</value>
</property>
<property>
<name>yarn.nodemanager.vmem-check-enabled</name>
<value>false</value>
</property>
<property>
<name>yarn.resourcemanager.address</name>
<value>hadoopresourcemanager:8032</value>
</property>
<property>
<name>yarn.resourcemanager.scheduler.address</name>
<value>hadoopresourcemanager:8030</value>
</property>
<property>
<name>yarn.resourcemanager.resource-tracker.address</name>
<value>hadoopresourcemanager:8031</value>
</property>
</configuration>
So I can say, I already tried your suggestion
Cheers
