Make sure the following exists:

fs.default.name value is local
2. make sure the machine name in your /hosts/search-servers.txt is
registered in your /etc/hosts or use the IP.
3. Make sure tomcat/webapps/ROOT/WEB-INF/classes/nutch-site.xml searcher.dir
value is set to /hosts
4. Make sure the Nutch user has access to /hosts
On your search server machine tail the log. the connection from tomcat
should appear.

FYI, I helped Monu to solve the issue. It turns out that the particular revision he is using was missing some later fixes, specifically NUTCH-217 and related fixes to Hadoop. After applying these patches it started working. Please be aware that if you use the latest pre-Hadoop version you will face the same issue, i.e. it won't work without patching.

One more note... It is not wise to put IP addresses in your emails.

Agreed.
