--------------------------------
[~natefalkibm] Hello Nathan,
For example, if you look under Advanced core-site section, the Ambari web UI
allows property "hadoop.security.key.provider.path" to be left blank (empty
value). This is controlled on the core-site.xml level as shown below....
<property>
<name>hadoop.security.key.provider.path</name>
<value></value>
<value-attributes>
<empty-value-valid>true</empty-value-valid>
</value-attributes>
Have you tried specifying properties to allow empty values to meet your
requirement?
It's of course up to component's Python script to handle what it means for a
prop to have an empty value...

> The only way to let a configuration property be optional seems to be to
> define it in site_properties.js. It should be possible to specify
> required=false for any property in any xml file in the stack.
