How do I update Sunspot-Solr's path after I change my Application Name

Normally my app was located here at :

/data/Site/current/

but now it's:

/data/Site2/current/

I tried to script/console into it, and reindex, and received the following error which lead me to believe that the new path is throwing it off:

How would I go about changing Sunspot-Solr's default dir?

This is because the sunspot-solr gems were not installed on the server thus all the call to gem errors here. When I installed my gems, I also had to kill its process with a pkill.

I ran

$> ps aux | grep solr

Saw it was running a process, so I ran a pkill :

pkill -term -f '/usr/lib/jvm/sun-jdk-1.6/bin/java -Djava.net.preferIPv4Stack=true -Dsolr.solr.home=solr -jar start.jar'

Killed it and restarted it. Problem solved.
