rake sunspot:reindex rake aborted! RSolr::Error::Http - 404 Not Found

Question

I can no longer reindex and cannot resolve this issue. Spend several hours digging the web for this issue. ** *regarding production environment * development goes ok. :( How would one fix this?

rake sunspot:reindex
rake aborted!
RSolr::Error::Http - 404 Not Found
Error:     Not Found

Request Data: "<?xml version=\"1.0\" encoding=\"UTF-8\"?><delete><query>type:Match</query></delete>"

Answer 1

upgrading to tomcat6 fixed the issue after i Set sunspot.yml path to /solr/collection1 and copying the scheme.xml from sunspot to the /opt/solr/collection1/conf/scheme.xml

Answer 2

These are the terminal commands you should follow to solve your problems:

1. ps aux | grep solr to get solr process ID
2. sudo kill <ID>, <ID> is the ID you found from 1
3. rm -r <path/to/solr>, remove the solr directory inside your project to remove all of previous indexes
4. RAILS_ENV=production bundle exec rake sunspot:solr:start
5. Change the path to /solr/default inside config/sunspot.yml
6. RAILS_ENV=production bundle exec rake sunspot:solr:reindex

Bam! Problems solved! I hope.
