```
Here, `COMPONENT_INSTANCE_NAME` and `SERVICE_NAME` are the constants to be substituted by the system.
Suppose the `COMPONENT_INSTANCE_NAME` is `regionserver-0` and `SERVICE_NAME` is defined by user as `hbase`, user name is `devuser` and domain name is `hwxdev.site`.
Suppose the `COMPONENT_INSTANCE_NAME` is `regionserver-0` and `SERVICE_NAME` is defined by user as `hbase`, user name is `devuser` and domain name is `dev.test`.
Then, the config will be substituted by the service AM and written in the config file `/etc/hadoop/hbase-site.xml` inside the container as below:
```
<property>
<name>hbase.regionserver.hostname</name>
<value>regionserver-0.hbase.devuser.hwxdev.site</value>
<value>regionserver-0.hbase.devuser.dev.test</value>
</property>
```
where `regionserver-0` is the actual component instance name assigned by the system for this container.
