Specify optional service config parameter without default value

Hi,

I would like to specify couple of service parameters which are optional and
don't have a default value.

I have specified my parameter in following way in config file:

<property>
    <name>datatorrent.config_file.path</name>
    <value></value>
    <description>Full path to existing dt-site.xml file to use for new
installation. Overrides default and previous dt-site.xml</description>
  </property>

Ambari doesn't allow the blank config value. Please check attached
screenshot.
Is there any xml tag in property which will allow me to skip optional
parameters?

This seems to work with Ambari version 2.2.2.

Thanks for all inputs.

Re: Specify optional service config parameter without default value

Posted by priyanka gugale <pr...@gmail.com>.
As I understand combination of suggested option should work. Can see it
being used in Kerberos service as well in Ambari repository:
 <property require-input="false">
    <name>domains</name>
    <display-name>Domains</display-name>
    <description>
      A comma-separated list of domain names used to map server host names
to the Realm name (e.g. .example.com,example.com). This is optional
    </description>
    <value/>
    <value-attributes>
      <empty-value-valid>true</empty-value-valid>
      <overridable>false</overridable>
    </value-attributes>
  </property>


But for some reason doesn't work for it. It still marks config parameters
are required. I am using Ambari version 2.0, is there any known issue?

Hi Priyanka,

Could this property option help on your goal: <property require-input="false"> ?

Hi,

I would like to specify couple of service parameters which are optional and don't have a default value.

I have specified my parameter in following way in config file:

<property>
    <name>datatorrent.config_file.path</name>
    <value></value>
    <description>Full path to existing dt-site.xml file to use for new installation. Overrides default and previous dt-site.xml</description>
  </property>

Ambari doesn't allow the blank config value. Please check attached screenshot.
Is there any xml tag in property which will allow me to skip optional parameters?
