More specifically, I found out the cause for my problem, hope this helps any souls who was wondering what happened

First, I deleted the solr/data folder. Bad idea. And this caused the errors as described by cakism.

Restarting, deleting solr folder, etc. won't help. Simply because there is an instance of Solr server running and it will not be stopped even with sunspot:solr:stop. You have to kill that instance by:

rake sunspot:solr:stop # stop server
ps -A | grep solr      # you'll see the [PID] of the solr server
kill [PID]             # replace with the [PID] from above to completely kill the solr instance

After this, you can then proceed with deleting the solr folder and starting the server again
