If its not in the app directory, then there it would be interesting to do a search and see if does exist at all. It may now be located somewhere in the user profile for better user control.
Xp / Vista - cmd - dir C:\spark.ini /s/b
linux / os x - find / -type f -name "spark.ini"
It may not necassarily be a .ini on non windows systems.
On OS X it could also be spark.plist
On linux / OS X it could also be spark.conf
Then again, looking at the code would show name and location.
