Hadoop Customization overwritten by Ambari -

It seems a simple task: change JAVA_HOME in /etc/hadoop/conf/ to use a different version of Java.

However, Ambari will, it seems, overwrite any changes you make in the, by using it's templating scheme.

The template seems to contain following line:

export JAVA_HOME={{java_home}}

So, now if this is used to generate and replace the environment on each node, how do I define the {{java_home}}?
