Yes, we used to do VolcanPlanner before but we switched in Hive 14 time frame (2014) due to
the performance limitations.
I am not sure why you are after VolcanoPlanner; but yes you can get back to VolcanoPlanner
and probably get it to work.

I know this because I did most of those changes back in 2014.
