Hi,
I am still facing the problem. Here is my updated configuration:
<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>
<value-attributes>
<empty-value-valid>true</empty-value-valid>
</value-attributes>
</property>
Even after adding this configuration it shows me the config is required.
