Enable the device plug-in framework

After you install the required software and enable the required configuration parameters listed as prerequisites for using the device plug-in, configure the yarn.nodemanager.pluggable-device-framework.enabled parameter in the yarn-site.xml file.

To enable the device plug-in, set the following property in the /etc/hadoop/conf/yarn-site.xml file on the ResourceManager host:
```
<property>
	  <name>yarn.nodemanager.pluggable-device-framework.enabled</name>
        <value>true</value>
	</property>
```
To enable the isolation native module, set the following property in the container-executor.cfg file.
```
<property>
	  <name>module.enabled </name>
        <value>true</value>
	</property>
```
