nutch-site.xml: Overwrite setting from nutch-default.xml with ""

Hi!

Is there a way to un-set a setting defined in nutch-default.xml without touching nutch-default.xml, but by somehow overwriting it with null in nutch-site.xml?

I've tried to set
<property><name>http.agent.version</name><value></value></property>
but that will just keep the default value.

Thanks!
Felix

Thanks,
I've tried <value>' '</value>, <value>''</value>, <value> </value> , <value>0</value>, <value>null</value> -- hoping that maybe un-setting was supported somehow, but they are all interpreted as literal strings. Ah well, it seems like I won't get around editing nutch-default.xml :)

hi,
it's logic when you dont provide a real value nutch will search for one on
nutch-default.xml, i suggest to try <value>' '</value>
