Hi Alex, I haven't seen this problem before.
Did you try to shoot a query manually to the frontend node? You can either use the web interface at http://ipaddress_of_frontend:8080 or just use the following command: curl "http://the.ip.address.of.frontend:8080/search.jsp?query=google"; In case you can shoot a query successfully, I would like to see your client configuration file. Can you please attach the following files? a) search/run.sh b) search/deploy/run.xml Also, is there any reason that the backend, frontend, and client instances run on the same server? -Stavros.
