IMportance of yarn-site.xml on slave nodes

[#1]

Hi ,

How the node-manager/slave understand that to communicate which resource-manager.

I am aware that we add this property in yarn-site.xml in the slave.

        <property>
                <name>yarn.resourcemanager.address</name>
                <value>master1.datatorrent.com:8050</value>
        </property>

But how to configure these properties if we have Resource manager (HA), that is two resource manager?

Take a look at this link for details on how to set up RM HA.
