Q:

RSolr::Error::Http - 404 Not Found

I got the following error when i tried to run "rake sunspot:solr:reindex". Does anyone has idea how to fix this? It used to be running fine until recently.

A:

I am new to solr and had the same issue getting it working in development.  When I ran everything as sudo, it started up with no problems: 
$ sudo bundle exec rake sunspot:solr:start
$ sudo bundle exec rake sunspot:solr:reindex

I could then view the solr server at http://localhost:8982/solr
So it looks like a permissions issue to avoid having to run it as root.
