    I'm sorry to give the feedback lately.
    I cleaned up duplicated codes.
    Could you check the patch again?

> Currently, Tajo just use hash shuffle for CTAS statement. If you use large 
> partitioned table for target table, you will see poor performance of wrong 
> task number. Thus, we need to calculate the number for the partitioned table 
> with scattered hash shuffle.
