> It seems that the partition prune rule may be fired multiple times, even 
> after the first rule execution has pushed the filter into the scan operator. 
> Since partition prune has to build the vectors to contain the partition /file 
> / directory information, to invoke the partition prune rule unnecessary may 
> lead to big memory overhead.
> Drill planner should avoid the un-necessary partition prune rule, in order to 
> reduce the chance of hitting OOM exception, while the partition prune rule is 
> executed.
